## Homework Statement

The problem asks us to find the equation for an isotropic oscillator in the form of an equation for an ellipse. I'm in PHYS 212, Analytic Mechanics.

## Homework Equations

x=Acost(ωt)

y=5Acos(ωt-.6435)

The equations I found for x and y.

## The Attempt at a Solution

So far I have the equation at y=5[x*cos(-.6435)+(1-x^2)^(1/2)*sin(-.6435)]

I looked in the example in the text for the original derivation, and it basically skips through this part. I need to know how to transpose the equation I got to further simplify my work.
