Ello again. The problem states:
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 [3,3.2]
(b) Write an expression for the velocity v(3)
(c) Write an expression for the unit tangent vect0or T(3) and draw it.

I drew the vector, and in b, i think that's what they want but I'm not sure, and with C, i drew the Tagent vector t, but I'm not sure about how to write an epxression for unit vecotr T. THanks.
