It is largely the same as a differential, a measure if how one quantity changes as a function of an input. In general, in the context of your current project velocity is the derivative of position, acceleration is the derivative of velocity, and jerk is the derivative of acceleration. I feel sure that you actually do know what a derivative is, if not necessarily by that name. The voltage drop through an inductor is proportional to the derivative of current (by time) http://en.wikipedia.org/wiki/Derivative -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
