(a) On a separate sheet of paper, sketch the parameterized curve x=tcost, y=tsint for 0≤t≤4π. Use your graph to complete the following statement: At t=6, a particle moving along the curve in the direction of increasing t is moving and

(b) By calculating the position at t=6 and t=6.01, estimate the speed at t=6. speed ≈

(c) Use derivatives to calculate the speed at t=6 and compare your answer to part (b). speed =
