Please help with practice problem 1 and 2.

1.

Find the velocity and acceleration vectors and the equation of the tangent line for the curve r(t) = 2 cos(t)i + sin(5t)j at t = 0. (Use symbolic notation and fractions where needed. Give your answer in the form (*,*).) v(0) = l (0,5) a(0) = l (2,0) (Use symbolic notation and fractions where needed. Give your answer in the form (*,*). Use t for the parameter that takes all real values.) Incorrect Find the velocity and acceleration vectors and the equation of the tangent line for the curve r(t) = ti + est j + 6e"k at I = 0.
