<p>Press "Edit" and try these: </p>

<li>x^2-y^2</li>

<li>-5*x*y*e^(-x^2-y^2)</li>

<li>abs(x)-abs(y)</li>

<li>(x^2+y^2)^0.5</li>
|
|
<li>cos(x^2+y^2-0.5)-0.5</li>
|
|
</ul>
|
|
<p>You can change "xMin", "xMax", "yMin" and "yMax" values, but at this stage the program is always c<b>entered on 0</b>.</p>
|
|
<p>The "xN" and "yN" control how many squares are plotted, go too low and it gets too chunky, go too high and the program really slows down and <b>uses up a lot</b> of your devices resources!</p>
|
|
<p>Also try changing the "zFact" to make the z-height more or less <b>dramatic</b>.</p>
