Thread: help in solving trigonometric Integral!

Hi Folks,

any helpful thoughts in solving the attached integral!

Thanks

Use technology for this one

integrate (((a+0.5*cos[x])co s[2x])/(a^2+a*cos& #91;x]+(cos[x])^2) ) - Wolfram|Alpha

Thanks pickslides

but the issues is that how to deal with the imaginary part of the solution, as the integral's solution is for a velocity distribution which is expected to be real!
