Secant Lines and the Derivative
Author: Steve Kifowit

This worksheet will help you visualize the tangent line as a limit of secant lines.

f(x) = (x^(2.0) - 2.0) / 3.0
A = Point(f)
B = Point(f)
a = Line(B, A)
b = Tangent(A, f)
c: f'(x(A))
m = Slope(a)
text2: "Slope of secant line = " + m
text1: "Derivative: f ' (" + (x(A)) + ") = " + c
