www.whitman.edudistance gives the average speed. As ∆t approaches zero, this average speed approaches the actual, instantaneous speed of the object at time t. So by performing an “obvious” calculation to get something that looks like the deriva-tive of r(t), we get precisely what we would want from such a derivative: the vector r′(t) points in the ...
