+jessybear345 Glad to hear it! I do recommend buying a copy of the "Using the TI-84 Plus" book to get more examples and easier reference material, since this video is based on that.
My MAT 103 professor decided yesterday (TWO DAYS BEFORE EXAM #3) that we needed a graphing calculator to complete this exam tomorrow (no, it wasn't mentioned in the syllabus or anything). This video series is an absolute GRADE SAVER right now. Thank you so much!!
i went from a ti-30iis to a ti84 plus ce and felt so lost this explains so much im going to watch the entire series and pick up a book thank you to much!!
+David Radtke You're most welcome! Comments like that are a great motivator to continue working on this series, which I've sadly let lapse in the past few weeks. :)
Thank you. I have less than a month to get myself ready for a college algebra course, and realised, in addition to everything else I need to teach myself, I also need to feel confident with my new calculator before class starts. I'd figured out a few basics (very, very basic things, like on and off, use of the alpha and 2nd keys). This first video has given me a taste of its capabilities. I look forward to the rest of the series and feeling less overwhelmed by the TI-84 Plus CE. I'll be adding the book to my collection before classes start next month, for more in-depth information.
It's a very informative video and I look forward to watching the rest of the videos. My only suggestion is that maybe you should zoom the camera in closer to the screen so we could see the screen more clearly. Other than that, great video. Keep up the awesome work
Thank you soooo much for this amazing and helpful video. I am about to be a 7th grader and I qualified for the Algebra 1 class. This video answered all of my questions and cleared all my confusion!
You're welcome; happy to help! Feel free to post any questions that come up (or of course I strongly recommend grabbing a copy of "Using the TI-84 Plus").
i just got my calculator for school a few dyas ago, and i am planning on getting to know it really well while i still have summer break, your tutorials will certainly help! (it's also really funny how people like me still comment on this video from 7 years ago :D)
Thanks! Glad they'll help. I'd make new videos, but I'm pretty happy with how these came out (except maybe some of the calculator screen videos could be a little clearer).
Hey! What can i say? This video helped me so much. My aunt brought me a TI-84 Plus calculator, and i didn't know how to use it. Well, i still have a little bit troubles with it, because i don't speak english perfectly, but i'm learning! So, with your help, i finally could understand how to delete number by number instead erase ALL. So, thank you so much! I send you greetings.
I'm glad I was able to help you use your calculator! Feel free to ask any questions, and to pick up "Using the TI-84 Plus, Second Edition", if you think the book might help you.
Thanks so much! I'm working towards my master's degree and was confident until this class. You explained the questions I had about this calculator. You're awesome thanks!
+Kina Williams I'm glad to help! If you have any other questions, I encourage you to grab "Using the TI-84 Plus, Second Edition", and/or ask them here or on Cemetech.
I L♥VE THIS CALCULATOR!!! It is most definitely an upgrade compared to the original TI-84X! And this calculator is ACT/SAT approved it too good to be true! Kerm the real MVP!!
Just got out of the military and I'm starting school for my BS in physics. Tried figuring out my calculator and was a little confused which made me double think my major ahahahahah, but this video helped me grasp it all now. You're awesome man, thanks for putting in the time to help explain this!
great video, thank you for making this informative guide. i was so confused about the trigonometry calculations, but then realized it was on the wrong mode.
excellent video, a lot to learn, as a teacher myself, i would think it necessary to have some simplified, block diagram, layout, patterns, of how to move your fingers around and get a generalized layout of this wonderful complex calculator, I am doing differential third order equations for radio work, radio site planning, and it is excellent,
Thank you so much for this video. I'm taking the CLEP test in calculus tomorrow, and have never yet used this calculator 😅. The series has helped a lot.
If you’re looking to purchase a graphing calculator, may I suggest a Casio fx-CG50, it retails for about half the price, and can do twice as much. (It’s got a periodic table on it and can 3D Graph.)
Mine won't turn on or off it turns off by itself after a few mins but then when u press on it doesn't turn on and I have to plug it in to turn it on and then when it is on and I press 2nd and the on button it just momentarily dims the screen a bit and doesn't turn off, please help school starts soon!!!!
It sounds like your ON button might be faulty. To double-check, hit the little RESET button on the back with the tip of a pen, and see if that fixes it. If not, call 1 800 TI-CARES and see if they'll replace it under warranty.
Thank you for this. I’m upgrading high school courses for better grades to get into post secondary after being out of school for longer then I’ll admit to… and this has helped me get back into the swing of it without struggling with the calculator too!!
I got a ti 34 when I was 11 I'm 13 now and still didn't know how to turn it off until today... I kind of do prefer my simple ti 34 because it is simple like my brain, and it's solar-powered so I don't need to carry my charger around with me because it doesn't have a charger. also thank you for making this video for simple brains like me who forget to read or try to read and can't understand/accidentally recycle their calculator instructions(i did all of those things) cause now i don't need to google everything(and i can move from basic life to advanced life)
I am planning on buying this, but any calculator after/complexer than the old TI-34 from the 80's(got it from my dad) is a total mystery for me when everyone in my class uses a Classwiz fx82ex so I get so disoriented. So thanks in advance and thanks in general!
Is there any way to not get decimal answers on this calculator? for instance I want to get square of 2 divided by 2 instead of getting 0.707 for sin(45)
if you have a regular calculator I would just put that in there. I usually have one regular one and one graphing calculator. But I think you could go into settings
I bought my TI-84 Plus CE but it is a little bit difficult for me understanding everythibg about my calculator, because all the videos are in english (I'm a spanish speaker), however I got many things as I can, thank you for made the video.
I'm trying to generate a random number. I had math and then I scroll to the right "PROB" , then I hit 5 "randNorm" . But every time I hit 5 I get a weird message, it says lower upper and paste? What does that mean?
It's asking you for the upper and lower bounds of the random number to generate. You can disable these so-called "Stats Wizards" in the [MODE] menu if you want. If you're trying to generate either a random integer or a random floating-point number, you should also look at rand and randInt.
KermMartian thank you so much! That was bothering me for quite some time. I disabled stat wizard now my Calculator is looking like everyone else in the classroom. I have a question. Do you recommend start wizards to be on? Is it something that you recommend? Or just depends on the situation that you're in?
You can create programs that store text, and you can also use text editors (like TextEditor CE on Cemetech, at www.cemetech.net/programs/index.php?mode=file&path=/84pce/asm/programs/TextEditCE.zip ) to view and edit text on your calculator.
Your calculator can't do that on the homescreen. However, there's a Solver in the [MATH] menu that can find the value of X given such an equation; the book ("Using the TI-84 Plus") explains how to use it. However, surely you can do that by hand, by multiplying both sides by 67.3 (38.46x = 7*67.3), then dividing both sides by 38.46 (x = 7*67.3/38.46). It's very simple algebra. :)
keep getting the wrong answer when I do a negative integer with an exponent...ie, -1^4=-1 or -5^4=-625...I'm getting wrong negative signs...Please help if you can. thanks.
This is an unfortunate but logical result. The exponent sign has higher priority, so it's applying the exponent first (giving you 1^4 = 1 or 5^4 = 625), then applying the negative sign. You can solve this with parentheses: (-1)^4 or (-5)^4. Good luck!
1. The comma is for specific functions that take multiple arguments, and for making lists. For example, the randInt() command (generate a random integer between two bounds, inclusive), takes two arguments, e.g. randInt(1,10) will generate a random number between 1 and 10. {1,1,2,3,5,8}->L1 will store the first 6 digits of the Fibonacci sequence to list L1. 2. Simply give them the angle you want the sine/cosine/tangent of, e.g. sin(45) or cos(π/6). Note that the [MODE] that you're in (degree or radian) will affect how the calculator interprets the angle.
I assume you've solved your problem by now, but if anyone else has this issue, you can go to [MODE], look for the row with "Full Horizontal Graph-Table", move the cursor to "Full", and press [ENTER].
@@KermMartian everything in the video worked except for this. I tried abs -3.2 but when I hit enter it gave me 3.2, not -3.2. I also tried closing the parentheses but same thing. Could it be this is an older version or is the answer 3.2 and not -3.2? Thanks.
Marwa Katir To do this you have to enable MathPrint. To do this hit the mode key, and the first line should have two options: MathPrint, and Classic. Select MathPrint. If these options don't show up, you need to update your operating system. You can look up how to do this on youtube, or you can ask your math teacher to do it for you, most know how to... Hope I helped!
Do you have a book like this which will teach me how to use the Nspire since it has a different keyboard than the TI-84 Plus or is the difference not noticeable enough to warrant one?
Which notes? Depending on which calculator model you have, you can use programs like Document DE to view text files on your calculator. You can also use SourceCoder ( sc.cemetech.net ) to type programs on your computer that you can edit and run on your calculator.
Thanks very much! Let me know if you have any questions I can answer, or feel free to stop by the Cemetech forum ( www.cemetech.net/forum ), where I've collected a friendly group of volunteers who can also help.
Thank you for commenting back to me. I'm in the 2.4 section of the "using the ti-84 plus" book. This book is very clear and easy to use. I recommend people who want take advantage of the ti calculator. I'm only in chapter 2 and I've learned more about using the calculator in this book than my whole life time. I'm 46 years old. This book is so addicting. I can't seem to put it down. Every page has some great examples to do. If I had to compare this book to would be like a Final Fantasy XIII strategy guide. I love playing Final Fantasy XIII and with the strategy guide. The game is even greater to play, finding secret treasures and weapons. So this "using the ti-84 plus" to me is a strategy guide book for calculator and all it's powerful apps. That's one of the reason I can think of. I read a little bit about the ti-basic too. I can't wait to order your "Programming the TI-83 Plus/TI-84 Plus". It' going to be another addicted book to have. I'm ordering 2 copies again for me and my grand daughter. To just have a complete collections I'm going to get the using ti-84 plus 1st edition from 2012. It's going to be awesome. Just want to say thank you Christopher R. Mitchell for these great books. I hope whoever loves using the ti calculator will get these books. It is a priceless knowledge to have. I can't wait to get those other two books. I do have one question. I upgraded to the 5.2.2 os and I can't seem to be able to drag any of the games into my calculator using the ti connect. But it's a simple taste that I can look up. I just wonder if it's an issue or it's just me not knowing what I'm doing. Thanks again.
Thanks for the kind words; that means a lot to me. I hope that you'll find programming the calculators to be another exciting challenge. Are these games that worked correctly on your calculator before you put OS 5.2.2 on it?
KermMartian i went to you cemetech site and down loaded that pacman game and try to put in my calculator. never done this before. but all the program i got from ti education channel worked. when i draged the pacman or any other games to the connect, the copy logo doesn't come up. but all the files from the ti education 5.2.2 will copy over the ti connect. it's no big deal. thanks for your time
No, unfortunately. The French version of this calculator, the TI-83 Premium CE, has an exact math engine that will do things like simplify radicals for you. Because of pressure from exam boards (eg, the SAT board) and teachers in the US, the TI-84 Plus CE has no such feature built-in. However, hopefully one of Cemetech's members will make a program to replicate this functionality soon. You can check out what's already available at www.cemetech.net/programs/index.php?mode=folder&path=/84pce/basic/math .
The TI-84 Plus CE can't solve algebraic expressions like the on the homescreen. However, if you go to the [MATH] -> Solver... tool, you can enter 2X+20 as one side of the equation using the [XT0n] key, 14 on the other side, and press [ALPHA][ENTER] to solve.
Could I get some help please? I hope you are familiar with the Collatz Conjecture. [Pick a number ~ if it is odd, then [*3, +1]. If it is even, then [Divide by 2]. Keep doing this. You will eventually reach a 4-2-1 loop.] Now, picture a chart with 0-100 on the bottom & 0-100 on the left side. The bottom row will be for the starting number. The left side will be for the highest number reached before dropping to the 4-2-1 Loop for that starting number. Can such a program be written?
Steven, I am indeed familiar with the Collatz Conjecture, and this could be written as a trivial TI-BASIC program. It's easier to share code somewhere other than a RU-vid comment - please make a thread here about this question, and I'll see what I can do: www.cemetech.net/forum/viewforum.php?f=19
The difference is negligible. The CE-T is the European model with a testing LED; the CE is used in the rest of the world. They're functionally identical as far as math features.
Ah, I see. There's no way around that, I'm afraid; it'll automatically switch to showing the answer in scientific notation if it would be too many digits otherwise.
Somewhere between 10 and 14 hours per charge, in my testing. If you use it for a few hours each day, you'll need to charge it at most once a week. I sometimes use my Radical Red TI-84+CE a few minutes a week, and it lasts for months between charges.
Is this still TI's most recent model? Also, I am wanting to purchase a calculator for Mathematics for Economists, Data Science (prob + stat) and Financial Analysis. Is the TI-84 good for statistics, probability, uni-variable and multi-variable calculus, time series, regression, correlation coefficient, linear algebra and full notation support?
The TI-84 Plus CE is indeed still TI's most recent model. It will do statistics, probability, time series, regression, numerical calculus tasks like definite integrals and derivatives at a point, and numerical linear algebra. It does not have a CAS (Computer Algebra System), so it cannot do symbolic indefinite integrals and symbolic derivatives, and other symbolic tasks. I hope this helps!
Thank you KermMartian. Excellent analysis. Does the linear regression, matrices, probablity, statistics, linear algebra, uni-variable and multi-variable calculus, time series, functions all come native out of the box or do I have to download these as plugins? I am mostly using it for Mathematics for Economists and Financial Analysts as well as Data Scientists and Policy Analysts. Data Science as an example is heavy probability, regression and statistics. I am embarking on MA in Econ - using Math for Economists and Econometrics and Financial Economics as well as Data Science using "r". Is the color version worth purchasing instead of monochromatic?
All of the features that I mentioned are available in the TI-84 Plus CE come as part of the built-in OS. With Back-to-School sales (see www.cemetech.net/news.php?id=863 ), the color one is actually cheaper than the monochrome one in many cases.
Heyo! I have a question. How do you enter sin, tan, and cos without the parentheses in the calculator because I'm trying to run a program and it requires sin, cos, and tan to have a comma after them
The only way to do that would be to literally type out 'S', 'I', 'N', ..... What program is this? I'm concerned that it's not something that's compatible with your calculator, if you're trying to type the code out yourself.
I got my calculator yesterday and I want to recharge it and when I use the charger the gave me seems to be loose on my calculator. Also the description says it lights up when charging or something like that but mine doesn’t it’s just plain gray
The LED that's next to the USB port on the side should light up orange (charging) or green (charged) when you plug it in - if you suspect a problem with the charging cable that came with the calculator, try another mini USB cable. In addition, the earliest TI-84 Plus CE models had a somewhat defective port, where you had to really jam the cable in to seat it properly.
