Element Detail
Slopetriangle
-
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create
with type "slopetriangle".
- Possible parent array combinations are:
-
{JXG.Line} t
- A tangent based on a glider on some object, e.g. curve, circle, line or turtle.
-
{JXG.Line} li
{JXG.Point}
- 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]);
