@@ColesWorldofMathematics Still helping people many years later. Thanks so much for the tips and memory helpers. I'm 47 and going back to school and even though I've done tons of math and physics, my memory just isn't what it used to be. These helped a lot along with your other videos.
A trick for memorising the sin, cos integral and derivative is to do: S -C C -S going clockwise from sine gives you the derivative going anti-clockwise gives you the integral. My teacher taught me this and before that, I used to think of its as a shift of the function's graph by 90. So sin(x+90) = cos etc and for each derivative, you add 90 degrees more, so f' '(x) = sin(x+180) which is just -sine for integrals, you do (x-90)
If there is one thing I miss about high school the most was how professors offered memorizing devices like these to students. Remembering sin and cos was relatively easy for me but the other 4 were a pain. This made it so much easier, thank you!!!
THANK YOU SO MUCH FOR THESE TIPS! I don't even remember how I ended up here, but I'm so glad I did! As a math/physics tutor (and student, for that matter) I'm ALWAYS struggling to remember all of these seemingly basic derivatives. Every semester I have to refamiliarize myself with each one of these, and this video organizes all of that information so helpfully. I'll be writing down all these notes and using them regularly for my students... can't wait to get to the integral version of this!
At first I was like "oh my gawwwwd, I have to remember all this???" but then I tried it and it turns out I can remember the chart so I'm good. haha. Thanks :P
You're welcome. When you get to Trig Integrals, you'll have a lot to memorize with those too. Be sure to check out this video for Trig Integrals: ua-cam.com/video/99WvTx29jt0/v-deo.html It uses the same chart!
I really love math but I could never fully enjoy trig. units because the straight up memorization was always so difficult. This helps a TON. Thank you.
The way I remember the anti-derivatives and derivatives of sin or cos is through a level system. If you imagine integration as going up a level and differentiation as going down a level then you just need to remember this: -c s c -s where for derivatives -cosx derives to sinx, sinx derives to cosx, cosx derives to -sinx and then it loops to -sinx derives to -cosx and vice versa for integrals. This is what I was taught by my maths teacher and it helped me out a lot, it's second nature now. When drawing the four letters I say in my head "C, S, C, S - Negatives at the ends"
this is absolutely phenomenal! god, bless ur dear soul for the amazing video. great quality, very quick, simple, right to the point and very well explained!
THAT"S F* GENIUS !!!!!!!!!! Lady you are the best!!!! OMGsh i was sufferring to memorize those derivatives and hiperbolic derivatives ,but now .. no more !!!! THANK YOU!!!!!!
I don’t understand the use of U’ yet, I have only learned up to the quotient rule and we haven’t covered the chain rule yet, if you’re only taking the first derivative of a trigonometric function do we need the U’ in our equation?
As long as the trig function uses a single "x" variable, you do not need chain rule (u'). In other words, as long as the trig function is not a composite function, you do not need chain rule (u').
We went over it, my teacher taught us to take chain derivatives by reading problems as two parts inside and out, our test on everything derivatives is tmrw and I’m gonna fail it 🤷♂️
I must inform you that all six equations written are not true. On the left side of each equation has the Leibniz derivative notation with respect to x. Then on the right of the derivative notation is a trigonometric function with u as its independent variable. Assuming x ≠ u, which was not stated, all six equations are simply wrong (they should all equal zero). You needed to keep both variables the same. The overall idea of this memorization tool for trigonometric derivatives is superb. Though most people glide across this small detail, if shown to a meticulous person it will not go without mentioning. Thank you for sharing this trick and allowing many people to learn from this video.
In the top right hand corner, it states that "u" is in terms of "x", meaning that the "u" in the formula represents a function written in terms of "x". This is common notation found in many Larson Calculus Books (written by Ron Larson).
For the longest time I've had to go back and memorize these before every test. You've saved me so much time I can't thank you enough.
So glad it has helped you! Thanks for watching!
Literally same

@@Hyvexx ahh sorry my bad. i used chat gpt earlier for this .this goddamn app gives me shit tons of wrong ans. ty tho
Pretty neat too!! Thanks for sharing!
Thanks a ton
the simplicity of your explanation makes me wish I had seen this when I was tutoring in the university math lab.
Thanks for the compliment.

You're welcome. Your statement is very true. Memorization techniques are always very helpful, and generally not shared or taught at the college level.
Very useful and to-the-point video; thank you, Ms. Cole!
You're welcome!

integral version is embedded. group up the first two from the left (or last two from the right) and you get the integral
