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...
Thanks ....I wonder how you could write the symbols of maths? is it the same sythax as lateX?
Hi sousou;
There isn't anything to show just the 2 substitutions and a small cleanup. I didn't do very much here.
Make your substitutions:
Pull out a factor of 2L inside the radical:
Thanks lobby,
but all what you did is substitution
I am looking for further simplification, I wanna get rid of the square root :
A = sqrt [C^2 + L^2 - 2*C*L cos (theta + phi)] = A = [C^2 + L^2 - 2*C*L cos (theta + phi)]^1/2///
and then expand the polynomial...
Hi sousou;
This is the best I can do after 3 tries :
A little simpler:
Thanks Bobby,
could you please show the detailed workout o fthe three tries ...Thanks...
Hello,
I need your help to expand the following:
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]
L is a constant.
Thanks for your help and time.
