Homework Statement
This question is part of Fourier Series in Circuit Analysis. There were fairly straightforward integrals which I calculated and confirmed using MAPLE to be correct, however the book gives somewhat different answers. I would presume that what I did was correct and the solutions manual made an error, however since it's a fairly large question with answers being carried forward I want to make doubly sure. Sorry about the size of the images, I will remove them after the problem
This is the integral essentially, the definite integral from 2 to 4 is left out because it's zero,
f(t) = 5 for 0 < t < 1
f(t) = 10 for 1 < t < 2

Homework Equations
cos (Pi/2) = (-1)[itex]^{\frac{n-1}{2}}[/itex]
cos (Pi) = (-1)[itex]^{n}[/itex]
The Attempt at a Solution
My answer came to this:

EDIT: cos(nPi/2) goes to (-1)^n/2 - still doesn't reconcile my answers with the book though.
The MAPLE output was:
[itex]5\,{\frac {1+\cos \left( 1/2\,n\pi \right) -2\,\cos \left( n\pi
\right) }{n\pi }}[/itex]
The answer in the book was (last line before the table):

As you can imagine, because the answers are different, the values in the table are going to be different and hence whatever I have to plot afterwards will be different.
