Use a CAS to perform the following steps.

a. Plot the space curve traced out by the position vector r.

b. Find the components of the velocity vector dr / dt.

c. Evaluate dr / dt at the given point t₀ and determine the equation of the tangent line to the curve at r(t₀).

d. Plot the tangent line together with the curve over the given interval.

r(t) = V2ti + ej+ek, -2 t 3, to = 1
