WebFeb 14, 2013 · 10. There are several ways to get estimates of the derivative at the i -th point. The simplest estimate is probably ( y i + 1 − y i − 1) / ( x i + 1 − x i − 1). This is just the slope of the line between the ( i − 1) -th point and the the ( i + 1) -th point. You'll have to do something special at the first and last points, of course.
