derivative of a power series
nan(x-c)n-1
integral of a power series
an(x-c)n+1 / n+1
1/1-x
∑xn = 1+x+x2+x3+…. R=1
ex
∑ xn/n! = 1 + x/1! + x2/2! + x3/3! + …. R=∞
sinx
∑(-1)n x2n+1 / (2n+1)! = x - x3/3! + x5/5! - x7/7! + …. R=∞
cosx
∑(-1)n x2n/(2n)! = 1 - x2/2! + x4/4! - x6/6! + …. R=∞
tan-1x
∑(-1)n x2n+1/2n+1 = x - x3/3 + x5/5 - x7/7 + … R=1
ln(1+x)
∑(-1)n-1 xn/n = x - x2/2 + x3/3 - x4/4 + … R=1
(1+x)k
∑(k n)xn = 1 + kx + k(k-1)/2! x2 + k(k-1)(k-2)/3! * x3 + …. R=1
