Hi Bernhard, schau mal unter [[Experimente]], da werde ich sammeln, wie man meine Theorie beweisen könnte. | Hi Bernhard, schau mal unter [[Experimente]], da werde ich sammeln, wie man meine Theorie beweisen könnte. | ||

Ich finde, hier sollte was stehen!
Hi Bernhard, schau mal unter Experimente, da werde ich sammeln, wie man meine Theorie beweisen könnte.
<html> <head>
<script src="http://www.till-meyenburg.de/lib/js/graph.js"></script>
<script> window.onload = function(){
var canvas = document.getElementById("myCanvas");
var myGraph = new Graph({
canvas: canvas,
minX: -10,
minY: -120,
maxX: 10,
maxY: 120
});
var context = canvas.getContext("2d");
myGraph.drawEquation(function(x){
return x * x;
}, "blue", 3);
myGraph.drawEquation(function(x){
return 100 - (x * x);
}, "red", 3);
context.font = "10pt TimesNewRoman";
context.fillText("Energie", 650, 120);
context.fillText("v(fort)", 650, 70); context.fillText("v(rot)", 650, 15); context.fillText("c", 354, 10); }; </script>
