I was asked to seek for a harmonic function u(x,y) in the 2-dimention disk whoes boundry condition is [tex]u\mid_C=A\cos(\phi)[/tex],the I need to calculate the integral [tex]u(\rho_0,\theta_0)=\frac{1}{2\pi}\int_0^{2\pi}\frac{(R^2-\rho_0^2)A\cos(\theta)}{R^2-2R\rho_0\cos{(\theta-\theta_0)}+\rho^2}d\theta[/tex],but I don't know how to calculate.
Thank for any ideas
