## Series Expansion

Plotter for functions given as a series Σ f(x, k). The expansions in a series can be compared
with different parameter ranges. For easier distinction, they can be displaced in y-direction.

For k and positive integer terms of k you may use the function fac(k) to calculate the factorial
which is often used in serial expansions.

### Example:

f(x,k) = x^(2*k-1)/fac(2*k-1)*(-1)^(k+1)
f1: k from 1 to 4 displaced by dy = 2
f1: k from 1 to 8 displaced by dy = 1
f1: k from 1 to 16 displaced by dy = 0
