Secant Lines and the Derivative

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

Visualize the Derivative

This applet helps you visualize the derivative of a function. Enter a function f(x) to graph; then move the yellow point on the graph of f to see how the derivative (shown in the right picture) behaves. Note: To enter an absolute value function, like |x - 1|, type [color=#0000ff]abs(x-1)[/color]
