Homework Statement
Represent 5x / (10 + x) as a power series, find c0, c1, c2, c3 and c4, find the radius of convergence
The Attempt at a Solution
I think I got the representation fine:
Ʃ from 0 to ∞ = 1/2 [ (-1^n)(x^n+1) / 10^n ]
Radius of Conv. = 10
But what the hell are those c0, c1 etc...? I thought they were the coefficients of the series but I keep getting them wrong...
My answers are: c0 = 1/2 , c1 = -1/20, c2 = 1/200 ...
Any help please?
