Question

convert the following parametric equations into a rectangular equation x=-2sinT y=2cosT

Answer 1

Hi Dakota,

               You want to eliminate T so you use whatever tricks or identities that you know to do that.

x²+y²=4sin²T + 4cos²t=4 so x²+y²=4 ( a circle with radius 2) is the answer
