Class Detail
Slopetriangle(t, li,)
- Parameters:
- {JXG.Line} t
- A tangent based on a glider on some object, e.g. curve, circle, line or turtle.
- {JXG.Line_JXG.Point} li,
- p A line and a point on that line. The user has to take care that the point is a member of the line.
- Throws:
- {Error}
- If the element cannot be constructed with the given parent objects an exception is thrown. Parameter options:
- Examples:
// Create a slopetriangle on a tangent var f = board.create('plot', ['sin(x)']), g = board.create('glider', [1, 2, f]), t = board.create('tangent', [g]), st = board.create('slopetriangle', [t]);
// Create a on a line and a point on that line var p1 = board.create('point', [-2, 3]), p2 = board.create('point', [2, -3]), li = board.create('line', [p1, p2]), p = board.create('glider', [0, 0, li]), st = board.create('slopetriangle', [li, p]);
