Sketch the graph of the following vector-valued function: 7(t) = (cos t)

Sketch the graph of the following vector-valued function: 7(t) = (cos t) i + (3 sin t) j , %3D 1) Introduce x and y to sketch the graph (we do not need to introduce z , why?). Let x = cost and y = 3 sint. 2) Eliminate the parameter t by using the following identity (cos 0)2 + (sin 0)2 = 1. We thus obtain x2 +=1. %3D 9. 3) Sketch the graph of and indicate the orientation of .
