Motion of a point on a curve in Mathematica
<p>I've been given an assigment to create an animation (in Mathematica) of a point moving along a curve created by the common part of an ellipsoid and a plane. </p>

<p>I've made the following as good as I could but I'm stuck.</p>

<p>The formula(?) for the ellipsoid surface and plane:</p>

<ul>
<li>Ellipsoid surface  <code>x^2/4 + y^2/9 + z^2=1</code></li>
<li>Plane <code>z=-x+2y</code></li>
</ul>
