In this video, I give a introductory tutorial on the Texas Instruments TI-84 Plus calculator, one of the most commonly used graphing calculators today.
Topics covered Include:
1. Turning on and shutting off
2. Basic operations (add, subtract, multiply, and divide)
3. Using the 2nd and Alpha buttons
4. Storing a value as a letter for later use
5. Navigating the mode window
6. Evaluating trigonometric functions
7. Evaluating with exponents
8. Using logarithms
9. Creating graphs of functions
10. Changing window and zoom settings for graphs
11. Calculating zeros and relative extrema of graphs
12. Graphing trig functions and using the zoom-trig feature

Also, if you hit the CLEAR button by mistake, and lose all your stack contents, you can just use the UP arrow key to get them back. Something I'm surprised the 89 Titanium didn't have since they both came out around the same time. This video does a very good job at getting one started.

@davidfrick2621 Год назад

EXCELLENT video! Seriously, very well done. No fluff or superficial content. The real value is the focus: what do you need to get up and running fast with this calculator. Good coverage of the essentials: trig, exponents/logs, and graphing. Everything else is pretty much intuitive but these are the critical functions people will need guidance with. And special thanks for demonstrating ZOOM 7 for graphing trig functions. Anyone who has to use trig functions is going to appreciate that one. Great presentation but the really superb part is the focus on the topics of substance; no wasted time. Thank you!

@terryterry7958 2 года назад

Actually, you don't have to use the change of base formula (although of course, it'll help if you have it memorized in your exams ;)), if you want to find log base k of x, you can do [log] [x] [,] [k] [)] (each key is enclosed in [ ]), where that [,] is the button above 7 (comma).

Sir, I have a question! My school needs a ti-84 plus CE calculator, but my mom only found and bought a ti-84 plus graphing calculator. Is it still okay if I go on using this to my classes or will I be left behind if I use this calculator? Is there really such major differences between them?

@progressivehouseclusive3835 Год назад

I noticed that your characters and digits go to the next line(8:27 in the video) instead of infinitely going all to the right. How or where in the settings do I change that?

@strixapades312 7 месяцев назад

I doubt you still need the answer, but you can do this by selecting MODE, pressing the up arrow, and changing from MATHPRINT to CLASSIC.

@hantaworm03bryant91 3 года назад

Can this calculator convert decimals into a fraction that has square roots in the answer? For instance 1.166190379 is equal to square root 34 / 5, but with that answer show up in the calculator in that format?

@TutorTerrific 3 года назад

Unfortunately, I don’t think so. I know that the TI 30XS multiview can do that, But it is much newer than this.

@rochakpaudyal 3 года назад

Hi! What’s up with the charging port? Do you mind explaining that since it take battery anyways.

@TutorTerrific 3 года назад

That is actually not a charging port, but a port for a programming cable. A cable comes with these calculators that allows you to connect to the computer to download programs.

It was indeed very nice how that was set up, but I have to be honest: I borrowed that calculator to make that video, and I no longer have it.

I didn’t make a separate video for it. But here’s how I do it (numerator/denominator) I do it this way inside parentheses and it works just fine.

@TimNoyce 2 года назад

Press [alpha] then [y=] and you get a minimenu, use the top choice to input a simple fraction and then you can do fraction sums and the answer will be given as a fraction.

@Naudir505 Год назад

My hero! Ive been reading physics and have used an app so i wouldn't have to buy a graphing calculator. Final exam is one week away and they don't let you borrow one either so I had to panic buy one. But now i have no clue how to use it since its completely different in how you have to arrange your equations and settings, this will save my ass! Thank you! Btw... Is there a way to store entire equations so you just have to put in the necessary numbers? Example: F = k × (x_1 * ×_2)/r^2 Have that equation stored so i can just change the "x" to the numbers i need? That would be awesome! I got the "ti 84 plus silver edition"

@TutorTerrific Год назад

You can only input and evaluate functions by plugging in the right side of the formula to the y= button. Then, use the table button to input values and see the outputs.

Go to the window button and adjust the xmin, xmax, ymin, and ymax so that the min values are less than the max values. Alternatively, press the zoom button and the 6 to reset the graph window to its default settings.
