Parametric equations provides a convenient way to draw curves. We will use the following parametric equation in this project.
x = 200*(math.cos(a*t) - math.cos(b*t)**j)
y = 200*(math.sin(c*t) - math.sin(d*t)**k)
In the equations above, t is the parameter. Let is range from 0 to 2π with very small increment. Use different values for a,b,c,d,j,k to draw the following shapes (you can see the their values in the title of the pictures):
