1. The problem statement, all variables and given/known data It is a really long word problem, but I only need help with integrating one part of the proble. 2. Relevant equations I need to know how to integrate 2+5sin((4*pi*x)/(25)) 3. The attempt at a solution I tried using the chain rule by first integrating the sin into negative cosine, and then integrating the inside, giving me: 2x-cos((4*pi*x)/(25))*(2*pi*x^2)/(25) Sorry, I don't know how to do all the symbols, or any of them really.
