okay so i need to make a spirogram (this one [ Register or Signin to view external links. ] )

and basically i have this code
import turtle
import math


def formulaX(R, r, p, t):
x = (R-r)*cos(t) - (r+p)*cos((R-r)/r*t)

def formulaY(R, r, p, t):
y = (R-r)*sin(t) - (r+p)*sin((R-r)/r*t)

def t_iterating(R, r, p):
t = 0 # It seems odd to me to start from 2*pi rather than 0.
down()

while t < 20*pi: # This loops while t goes from 2*pi to 20*pi
t = t+0.01
goto(formulaX(R, r, p, t), formulaY(R, r, p, t))
up()


def main():
R = int(input("The radius of the fixed circle: "))
r = int(input("The radius of the moving circle: "))
p = int(input("The offset of the pen point, between <10 - 100>: "))

if p < 10 or p > 100:
input("Incorrect value for p!")

t_iterating(R, r, p)

input("Hit enter to close...")

main()


how would i fix it ? heres a link to the website where i found this if you can make more sense of it! Thanks!!!!!! [ Register or Signin to view external links. ]
