This example shows how you can change the equation of a graph without creating the whole construction again.



HowTo of this construction

Adding a text input field somewhere on the page 

<input type="text" id="eingabe" value="Math.sin(x)*Math.cos(x)">

Setting up the board 

  board = JXG.JSXGraph.initBoard('jxgbox', {originX: 250, originY: 250, unitX: 40, unitY: 20});
  // Axes
  b1axisx = board.createElement('axis', [[1,0], [0,0]], {});
  b1axisy = board.createElement('axis', [[0,1], [0,0]], {});
