Can someone explain how to do this: Consider the following parametric equations. x = 5cos(θ) y = 9sin(θ) 0 ≤ θ ≤ 2π (a) Eliminate the parameter to find the Cartesian equation of the curve.

Recall that $\displaystyle \cos^2(\theta)+\sin^2(\theta)=1$. Then write $\displaystyle 9x=45\cos(\theta)~\&~5y=45\sin(\theta)$ Square and add. Finish?
