Dot Product v1.0This program will find the dot product of two vectors/points, u=(u1,u2) and v=(v1,v2)/ <u1,u2> and <v1,v2).
Trap Rule 2.0This program helps you find the integral under a curve using the trapezoidal rule.

Derivative Guess v1.0This program helps you find the limit/instantaneous rate of change/derivative of a function at a point. You put in the equation and x-value and the program finds: the y-value at that point; the average rate of change from .1 away, .01 away, and .001 away; from which you can make an estimate of the limit, instantaneous rate of change, or derivative at that point.
