I tried to integrate the part after the cosine. I took out the "x" and got (x^2)/(2) and then multiplied it back into the (4*pi)/(25), and simplified it to (2*pi*x^2)/(25).
Do I instead not bother with the inside of the cosine, and just leave it as is, as in (4*pi*x)/(25)?
Homework Statement
It is a really long word problem, but I only need help with integrating one part of the proble.
Homework Equations
I need to know how to integrate 2+5sin((4*pi*x)/(25))
The Attempt at a Solution
I tried using the chain rule by first integrating the sin into...
