taylor series expansion for a square root...

Hello,

I need to find the taylor series expansion for a square root...

A = sqrt [C^2 + L^2 - 2*C*L cos (theta + phi)]

               Where:    C = sqrt[L^2 + (X + Y)^2]
                              phi = atan[(X+Y)/L]

A = sqrt [L^2 + (X + Y)^2 + L^2 - 2*sqrt(L^2 + (X + Y)^2)*L cos (theta + phi)]

Thanks for your help...

Hi sousou;

In terms of what variables and around what? To what accuracy?
