Here is a link to the powerpoint presentation from this session.

---

We started with a small group activity calculating

• dr vector in curvilinear coordinates.

Then we calculated

• the electrostatic potential due to a ring of charge.

This calculation is just one activity in a sequence that allows students to build up their understanding of how to do complicated integrals on step at a time.

We ended with a discussion of what the electrostatic potential looks like geometrically and how we might graph it. (See the graphs on the powerpoint presentation above.)
