For example, if you enter <maple>x^2/y^2</maple> you will get this image: 
Any Maple syntax will appear, so you can get complicated and enter this: <maple>sum(cos(x^2)/sin(exp(y)),x=1..infinity)</maple> which then appears as this image: 
Note that Maple will perform some simplification on your Maple syntax, for example, <maple>2+2</maple> will become
You can also enter any math syntax using MathML. Any MathML tags will be replaced with a 2D GIF image of that MathML.
For example, this syntax:
<math xmlns='http://www.w3.org/1998/Math/MathML'>
<mrow><mo>-</mo>
<mrow>
<mrow>
<mrow><mfrac><mn>1</mn><mn>90</mn></mfrac><mo>⁢</mo><msup><mi>h</mi><mn>5</mn></msup>
