      <itunes:summary>&lt;p&gt;You can use the explore command to see how the shape of the curve is affected by the parameters a &amp;amp; b.&lt;/p&gt;
&lt;p&gt;Type in:&lt;/p&gt;
&lt;p&gt;Explore( plot3d( b*exp(a*x^2)+y^2 , x = -10 .. 10, y = -10 .. 10) );&lt;/p&gt;
&lt;p&gt;Choose 'skip' for x &amp;amp; y in the subsequent dialog box and change a &amp;amp; b to whatever range you'd like.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;For example, try a from 0 to 0.1 and b from 0 to 100.&amp;nbsp; You can then explore the plot of the expression using the sliders.&lt;/p&gt;
&lt;p&gt;Hope this helps.&lt;/p&gt;</itunes:summary>
