Love your stuff man, you definitely deserve making money from this, and the ones you post anyway are still very helpful, so from the bottom of all of us to you, THANK YOU.
I see a lot of comments talking about studying a couple days before the exam but for someone whos been struggling to figure out calculus for the entire semester, your videos are a blessing. Thanks to you I can walk into my class with the confidence that I will do well. Thank you.
I have my calculus final in less than an hour and honestly, I've learned more in this video than I did from any of the lectures I've been at all semester. Thank you Mr. Tutor Man, I hope you understand how greatly you help people with what you do.
@@pabloescobar4029 its not always the students' fault. shitty professors, ADHD, etc. are a lot of factors that play into struggling to learn, even if youre trying your hardest.
@@Frysken take some responsability. If you have to study at 5am, sleep deprived, 3 hours before your exam, it is completely your fault and you are doing something wrong
I have my calculus exam tomorrow at 8am. I've learned and conceptualized more from this video than any lecture I've attended all semester, thank you greatly
@@Ben.N doesnt need to since he already made a video on it, but he would profit and so would we since it means more practice problems for us and more views for him
@@Kewbix 4. I think I was probably close to a 5, but I'll never know. So glad its over though and I can probably prepare myself better for BC next year.
Thanks dude! You've been a major help for me this entire semester. I've always been terrible at math and calculus really scared me. When I learned that I had to take calculus for my degree, I was scared out of my mind but, your videos helped me understand the subject much easier than I would have on my own!
YESSS YESSS YESS THE LITERAL BEST GUY MADE A REVIEW RIGHT BEFORE MY FINAL AND ITS UNDER AN HOUR LETS GO ILL UPDATE YALL ON MY FINA GRADE BTW I NEED A 60 TO PASS
H-how did you feel? I was soooo worried when I took it. I might have gotten a 3? probably a 2. Very very potentially a 4 if I did super well on the multiple choice.
@@marshp1999 Oh I definitely feel you. I got incredibly tripped up on the free responses, mostly on the ones with calculator. I’m worried about my mcqs since they could really make or break my exam score.
Dude I hope you realize how many people you've helped that you'll never even meet. Few people in the world have made this much of an impact in other people's lives. You may not be a celebrity, or a politician, but you definitely made a positive difference and without charging any money at all and for that you're a really good person. Alright...now onto my exam.
Shortcut for derivative of a function of type: f(x) raised to g(x) Let f(x) be f Let g(x) be g Let derivative of f(x) be f' Let derivative of g(x) be g' d/dx(f^g)=(f^g)(f'(g/f)+g' log(f)) For those who couldn't understand what's written above, It reads as: derivative of f raised to power g is equal to f raised to power g times (derivative of f times g by f + derivative of g into log(f))
51:55 you could also use L' Hospitals rule since plugging 4 into the original equation would give you 0/0. According to L' Hospitals rule, in a situation like this, you should be able to take the derivative of the top (-1/x^2) and put it over the derivative of the bottom (1) then plug in 4, which would give you -1/16 as well.
I would like to thank you so much OCT, whoever you are ☺️☺️. I started going back to school during the pandemic and started from Algebra 2 and yesterday I just finished my Differential Calculus final and got a 95.97%. Out of all the math youtubers, I watch you the most. I’ve used you throughout Algebra 2, precalculus, trig, and lastly Differential Calculus and received high A’s all throughout. I’ve always been super terrible at math ever since I was a little kid. I remember staying after school just to finish doing problems because I was one of the last ones to finish the problem set. I’m very thankful that you’re able to provide me with such great resources and just wanted to let you know you’re doing a great service to the American educational system. I cannot thank you enough!!! I will be using you for future science courses and of course, the dreaded OCHEM course I have to take 😣
i also take the longest to finish my math exams, always the last one left in class i have no idea how others do it. how long did you have to study per day to get better at calc and other topics?
Thank you for this video, I needed a refresher from a semester away from calculus going into calc 2. This helped reinforce the concepts from calc 1. Thank you for you time and effort into making this.
Hi, Is there a mistake on problem 2 (4:35 ish). Is it missing a negative sign? Or am misunderstanding the steps? I think the final answer should be: 6 x^5 - 3/x^2 - 1/(2 sqrt(x)) Still a very useful video. Thanks!
So watched this as well as part two litterally the night before the exam, got an 89. Lost points on evaluating limits (yeah ik right) and because I didn’t properly know what an inflection point was(again ikr) other than that I got everything right. Def helpful on the exam, the really hard questions I was sitting there like “oh yeah this dude mentioned this” but yet I got the simple questions wrong. Def study both
I've been doing an online accelerated calculus 1 class all summer and when I've had questions I've referenced your videos. You've been a big help to me this semester and I'm so glad I was recommended your channel.
I've always watched your videos, even though I didn't have an account, I still loved your videos! Now, since I have an account, I want to say keep up the great work! Thank you so much!
Am I mistaken or there is an error at 3:53: 1/2x to the power of1/2-1 must have “-“ in front not “+” …!!!!Yes! Final answer is correct!!! With the “-“ sing!
@@solar_cpg8833 Shortcut for implicit differentiation Take all the things on one side then do as below: dy/dx= -(diffentiate wrt x, take y as a constant)/(differentiate wrt y, take x as a constant) Eg. Lets say I need to differentiate x³+3xy=y²+1 Step1 (taking everything on one side) x³+3xy-y²-1=0 Step2 differentiate x³+3xy-y²-1 wrt x and take y as a constant That would be equal to 3x²+3y Let 3x²+3y = m Step3 differentiate x³+3xy-y²-1 wrt y and take x as a constant That would be equal to 3x-2y Let 3x -2y = n Step4 Apply the rule and obtain dy/dx dy/dx = -m/n = -3x²-3y/3x-2y This may look like this is quite lengthy but in actual it hardly takes 10secs. I wrote this long so that you can clearly make sense of it and understand
This is a good video, but I think the problems are way too easy especially for people in college. I did all of the questions in under 25 minutes. These certainly would not prepare anyone for the FRQs.
currently watching the night before my exam im excited ngl , one key take away is having a general understanding of what everything means , then doing a of examples
You got question 2 wrong. You reversed the sign on -x^1/2. Other than that this barely covered anything... Maybe 70% of what was covered is in the premium? Still given the mistakes I am not inclined to pay for your services. But keep up the good work and improve.

No exam coming up for me, but this video is certainly good for an early summer refresher on calculus! Gonna blow through 1, 2, and 3 before college starts again
