3. The orbit of a comet is a curve f(t) = (2 sint, cost). (a) What is the velocity of a comet as a function of time? (b) What is the acceleration of the comet as a function of time? (c) When are the velocity and acceleration perpendicular to each other? (d) Give an expression for the length of the trajectory when t [0, 1], (no need to calculate). 3.
