Explore the Slope of the Tangent Line using the Slope of Secant Lines[br][br]1. Type in any function[br]2. Choose the point of tangency[br]3. Slide X value and note the slope as x approaches a.

Estimate the Slope of the Tangent Line to each function at the given point.[br][br][b]1.[/b] [math]f(x) = x^2; at x = 1[/math][br][b]2.[/b][math]f(x) = (1/3)x^3 + (1/4)x^2-3x +2[/math]
