Stumped on Parametrics Question...
Hi,

I got an assignment and I'm close to the end but got stuck with one question that I tried but haven't been able to solve. I don't know how to solve it...any help is appreciated :)

Question is:
Find the Cartesian equation of the curve whose parametric equations are:
x=sin2t, y=cos^2(t)

Thanks,

Note that from the usual double angle formula, $\cos^2(t) = \frac{1}{2} \left(\cos(2t) + 1\right)$.
