Hello I have these instructions to solve an instantaneous velocity problem and I don't understand what does it mean by "differentiate the expression" in part b. (a) Use ∆x/∆t. To calculate the particle's coordinate at the beginning of the interval substitute into the equation for and to calculate its coordinate at the end of the interval substitute . , of course, is the difference and is (b), (c), and (d) Differentiate the expression for the coordinate with respect to time and evaluate the result for t=2s. Do the same for t=3s and for t=2.50s.
