2. a) Sketch and identify the curve defined by the parametric equations. (x (t) = t2 - 2t ly (t ) = t+ 1 N L+ -2 1-3+ -4 - b) Eliminate the parameter t to rewrite the parametric equation as a Cartesian equation. 3. Eliminate the parameter t to rewrite the parametric equation as a Cartesian equation. Then, sketch and identify the curve defined by the parametric equations. (a) Jx(t) = 3sin(t) Jx(1) = 6cos(t) ly(t) = 3cos(t) ( b ) Ix = ebt ly(t) = 3sin(t) () = e 12t (Think, will x be a negative number?)
