public class WCMTangentLineBean
extends WCMDrawGeometricBean

This bean draws a tangent line to a function. Use setFunction(Function f) to set the function and use setXValue(Value x) to set the location of the point of tangency. To draw a tangent to a parametric curve, use setXFunction(Function f) and setYFunction(Function f) and setTValue(Value t) instead.
