[tex]\int[/tex](Acosx + Bsinx + C)/(acosx + bsinx +c) dx
where the limits of integration are -π and π
The Attempt at a Solution
My question is: is the function periodic (I'm guessing it is, as it's a combination of sin, cos and constants?)
and, if so, is its period 2π (as sin and cos are of period 2π
and, if so, can we change the limits of integration to 0 and 2π without changing anything else (this would make sense to me)?
Can we do this in general for periodic functions - shift the limits of integration on by a certain number if they are the period?
Thanks for any help
P.S. I know you're supposed to show your work, but I can't really think what else to say!
