Although there is built in function to draw a circle in Turtle, let’s draw circles in a different way with parametric equation. The parametric equations for a circle is very simple:
x = radius*math.cos(t)
y = radius*math.sin(t)In the equations above t is the parameter, x, y are the coordinates of the points on the circle. Let t start from 0 and go up to 2π gradually.
