Question

Graph each pair of parametric equations.

x = 3 sin^3t
y = 3 cos^3t

Answer 1

you could plug in values of t to find what (x(t),y(t)) is

Answer 2

for example when t=0 we have the point (x(0),y(0))=(0,3)
and then you could plug in t=pi/4
plug in t=pi/2
plug in t=3pi/4
plug in t=pi
plug in t=5pi/4
plug in t=3pi/2
plug in t=7pi/4
plug in t=2pi which gives you (0,3) again so after this is going to just repeat
