How can i translate a parametric equation to cartesian

145 Views Asked by At

The parametric equations are : $$ x=16\sin^3(t)$$ and $$y=13\cos(t)-5\cos(2t)-2\cos(3t)-\cos(4t) $$

with $t$ from $-\pi$ to $+\pi$

so I'm new to this kind of equations and i really don't know how to start the conversion... Can someone help me?
