Homework Statement
I need to integrate
(2/a) [200sin(3*Pi*x)sin(n*pi*x/a)] from 0 to a. In this equation , 'a' is a constant. I don't have to show my work, just the final answer.

The Attempt at a Solution
I used a website, and got a result which I have attached. This online calculator does not plug in the bounds. However, this doesn't seem correct to me. I tried to integrate it by parts (to check), but couldn't get it to work. Any help? Thanks.
