1. The problem statement, all variables and given/known data Eliminate the parameter and express in x and y x= 2-3cos2t y= 5+7sin2t 2. Relevant equations 3. The attempt at a solution I tried changing them in terms of cos^2t and sin^2t. I change the first equation into ((x-5)/6) = cos^2t. But I can't figure out how to change the second one in terms of sin^2t.
