Recall that for |x| < 1, we have

$\displaystyle \frac1{1-x} = \sum_{n=0}^\infty x^n$

Differentiating both sides gives

$\displaystyle \frac1{(1-x)^2} = \sum_{n=0}^\infty nx^{n-1} = \sum_{n=0}^\infty (n+1)x^n$

and multiplying both sides by 8 gives the series for f(x) :

$f(x)=\displaystyle \frac8{(1-x)^2} = \boxed{8\sum_{n=0}^\infty (n+1)x^n}$

and this converges over the same interval, |x| < 1, so that the radius of convergence is 1.

Eric shades 4/6 or 2/3 of the whole blue
8/8-2/8=6/8
now he shades 4 out of the eight
so 4/8 or 1/2
