this is wild, thank you so much for being so detailed and sequential
Excellent video, thank you for making it.
Where is this angle theta taken from in the right angle triangle sir ?? And why??
I'm using trig substitution to solve the integral, so theta is just a dummy variable, it doesn't have any practical meaning in the diagram.
So, since it is just dummy vrble,... Can i make let y=Rcostheta then???
@@LEEHYORISARANGHEIO you can, but doing a trig sub we usually use sin for our sub b/c it's derivative is positive, derivative of cos is negative, introduces a negative sign to integral, not a big deal, just something to remember.
