\vtop{\hsize=4.25in \noindent {\bf Problem statement} A window is in
the shape of a $2'$ by $3'$ rectangle surmounted by a
semicircle. Describe the boundary of the window as $r=f(\theta)$ in a
polar coordinate system whose location and orientation you
specify. The $f(\theta)$ likely will need to be defined ``piecewise''.

\medskip

\noindent {\bf Comment} A calculus course traditionally has a problem
concerning this sort of window, including the rather uncommon word
``surmount'' as part of the description. Tradition is honored here!
