So, apparently there are more ways to solve for force, velocity, and acceleration than I ever dreamed of during calculus. We didn’t even discuss our lovely friend, the integral, until this morning, and then only to dismiss her in most of the practical situations we handle. Don’t worry, Sabrina, you are still awesome and curvaceous, and you acquire new fans daily wherever calculus is taught. No other can limit and sum with such precise grace as yours, no sign can describe the avs relationships with such tact, and none, none has such economical notation. Give my regards to your body guards – dx, dt, and the lot; I am certain we shall meet again soon.
