ok I am give a parametric equations of(adsbygoogle = window.adsbygoogle || []).push({});

x= 4 cos t and y=5 sin t

I know that i have to solve the x equation for t then stick it in the y equation but i getting stuck or not rembering some simple stuff i should be.

I believe i get t= cos(inv) (x/4) and substiute it in to t in y.

if so how so i simplify

5 sin(cos(inv)(x/4))
