Question

Find the rectangular equation of the curve whose parametric equations are x=-2sin t and y=cos t, where 0 less than or equal to tis less than or equal to 2pi.

How do I do this???

Thanks for all of your help!!

Answer 1

x^2/4 + y^2 = 1

That would be an ellipse with semi-major axis = 2 (horizonal) and semi-minor axis = 1 (vertical).
