I'm stuck on the second Step II calculus question.
Making the substitution of x=π−t, the integral becomes ∫0π(π−t)f(sin(π−t))(−dt)
The hints sheet seems to imply that I can just change all the t's to x's (which would then give the required result), but I don't think that could be right because x≠π−x.
I've got it
They have the same value b/c they're definite integrals.
Hehe
Well I was going to reply but it looks like you answered your own question! Nice demonstration of the value of leaving something and coming back to it later (and possibly sleeping on it?)
