Description: 
This activity demonstrates one of the many ways Sketchpad can be used in a calculus or math analysis class. Students manipulate a tangent line to a curve to investigate what it means for a curve to have slope. They explore the first derivative as a function which determines the slope of the curve for different values of x and express the derivative as a limit statement.
