A Yoda Revolution

This semester, I’m teaching Calculus II. Yesterday, students submitted homework on finding volumes of solids of revolution. As a quick primer on these shapes, a solid of revolution is generated by rotating a planar region about an axis. For instance, rotating the right triangle below about the vertical axis generates the cone to the right. […]
