How can we find the integral with the substitution ? I know how to find the integral, but the limits become the same sin(0) = sin(pi) = 0. What should I do in general when a given substitution makes upper bound = lower bound?

Using a different property, you can analyse the integrand as a function with period "pi", the (signed) area of which equals zero after each period.

Okay. I do see how the integral is zero. I just want to know what to do in general when a substitution makes the limits the same.
