I've been listening to this for almost four years now. Thank you for keeping me sane through all of the painful homework I've had to push through.

[parthdabas]

while opening rt(cos^2(x)) why didn't you use modulus that change the results?

[Nathanshin-lk]

what about the absolute value l cosu l

[rafaelpassareli]

Why do not call (x) to cos(x)? The answer will arccos (x)...?

[lakeshsahu...]

Thanks man, it's really very helpful 💝

[nik_semperlotti]

What about x=cosθ the antiderivative this time would be - acos(x)

[lorenzoantoniodeleon]

thank you so much, very simple and understandable

[neozoul]

Hey, is it okay if l replace x with cos u instead of sin u

[THBDubstep]

Where does the sin(x) come from..? I am so confused :( EDIT: I understand that it's substitution, but how would I know x^2=sin/..??

[winner]

0:20 pls explain x = sin(u)
why sin(u) ? why not tan(u) or cos(u) ?

[treymtz]

Anyone know how to solve this when the instructions are to NOT use Trigonometic substitution??

[itzzakshay]

Plz more videos on integration and disintegration

[mahmoudtony]

Great 😍...could you complete your great series of organic chemistry ❤❤?

[dharmik-sanatani-zo]

Please make a video on integration of 1 upon root(1-x)

[rehamelgaml]

I want this, please
y =x int dx (1-x^ 2 )x^ 2

[jasminemikasa]

Can we do this without trig substitution?

[ayushmishra]

Man, you have uploaded the same video twice

[HunterNapier]

Really wished you'd taken a little more time to show how it is arcsin. Still lost on that.
