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.

Class Detail
Tangent(g)
// Create a tangent providing a glider on a function graph var c1 = board.create('curve', [function(t){return t},function(t){return t*t*t;}]); var g1 = board.create('glider', [0.6, 1.2, c1]); var t1 = board.create('tangent', [g1]);
- Parameters:
- {Glider} g
- A glider on a line, circle, or curve.
- Throws:
- {Exception}
- If the element cannot be constructed with the given parent objects an exception is thrown.
