Hey guys! I'm not from an English speaking country so I'll do my best to translate. I would appreciate if you could help me with this problem.
1. Homework Statement
Increasing (growing) function is f(0)=0 and f(a)=b and a,b>0
Use ∫(from 0 to a)f(x)dx=ab-∫(from 0 to b)f^-1(x)dx to solve ∫(from 0 to 2)arcsin(x/4)
3. The Attempt at a Solution
I know how to find ∫(from 0 to 2)arcsin(x/4) so that's no problem but I just don't understand how I use the other part to find it, what am I supposed to do? Help would be appreciated!
Thanks in advance!
