<li>
 What is the difference between the tangent vector to a curve at a point 
$P$ and the <i>unit</i> tangent vector to a curve at a point $P$?

<li>Are there any values of t for which the 2D vector function $\myv r (t) = \myc{t^2 − 2t, \sin \pi t + \pi t}$ has a cusp? If so, find them. If not, why not?
<li>Muddy questions? Questions you wonder about?
