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...

Re: taylor series expansion for a square root...

Hi sousou;

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


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
