I would take and multiply both sides by
this gives
and using
r = cos(4*theta), x = r * cos(theta), y = r * sin(theta)Write the polar equation r = cos(4*theta) in the parametric form x = x(t), y = y(t)
x = cos(4*t) * cos(t)
y = cos(4*t) * sin(t)
Do the functions have to be in terms of t or can they be in theta?
Am I correct?
