By parts
I reckon
But I'm not sure
I couldn't
I don't have paper on me
It can't be solved by byparts
ye dekh ke haath seedha Save and Next par jaata hai
Lol
Lmao true.
Oh wait this diverges at π/2 na?
Yup the red lines are plus minu pi by 2
This goes in my mind currently, I've just got an idea of iterated integrals, but is that what I think right?
Can we multiply two integrals as such?
,rotate
You can, but not how you'd imagine. It would have to be independent variables and a double integral
So it doesn't help
So my idea of cancelling tan²x with cot²x won't work?
Nope
Ohk lol
What can we do about it? To make it into a double integral?
I was never actually thought about double integrals, I just saw a yt video of working with them
How can we multiply them in what way?
This integral is non-integrable btw
It diverges
Goes to infinity
Did you try any convergence test?
