Problem Finding Integral equation for 2*Cos( a*x) *Cos(b/x)

  1. Nov 6, 2008 #1

    I'm struggling to create an integral equation for

    Integral 2 * Cos( a*x) *Cos(b/x) dx

    Has anybody seen a potential solution for this. Mathematica online can solve each part individually however it is unable to create the integral for the entire equation.

    Hi CAP71! Welcome to PF! :smile:

    (have an integral: ∫ :wink:)

    Apart from writing it cos(a*x + b/x) + cos(a*x - b/x) and then maybe expanding it in powers of x, I don't see anything. :blushing:

    Thankyou Tiny-Tim for your response. I will look further into using the expanding powers method. I didn't think there was going to be a straight foward integral equation however I was trying to be optomistic.
