How to solve it using Python?

1. Write a function called spirograph which takes input parameters r, m, a and N, all integers greater than 0, and plots the parametric curve x(t) = r(m-1)cos(t/m) + acos((1-1/m)t) y(t) = r(m-1) sin(t/m) _ a sin((1-1/m)t) for t E [0, 2m]. The plot uses N evenly spaced t values from 0 to 2nm (inclusively). Include a title which displays the values of r, m and a. Use plt.axis'equal') and plt.axis('off') to display the curve clearly. The function returns a 2-dimensional NumPy array (of size N by 2) such that the array of x values (of size N) is the first column and the array of y values is the second column of M
