Class Tangent


Extends JXG.Line.
With the element tangent the slope of a line, circle, or curve in a certain point can be visualized. A tangent is always constructed by a glider on a line, circle, or curve and describes the tangent in the glider point on that line, circle, or curve.
Defined in: Line.js.
