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.
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
