1. The problem statement, all variables and given/known data r(t) is the position of a particle in the xy plane at time t. Find an equation in x and y whose graph is the path of the particle. Then find the particle's velocity and acceleration vectors at the given value of t. r(t)=(cos2t)i+(3sin2t)j, t=0 2. Relevant equations 3. The attempt at a solution x=cos2t y=3sin2t x2=cos22t y2/9=sin22t I'm not sure if I'm on the right track with this! Can someone please give me a push in the right direction?
