The figure shows the curve C traced by a particle with position vector r(t) at time t.
(a) Draw a vector that represents the average velocity of the particle over the time interval 3 < t < 3.2.
(b) Write an expression for the velocity v(3).
(c) Write an expression for the unit tangent vector T(3) and draw it.
