We will do some of the problems from the back of the chapters that involve math as well as supplemental problems. The math level is basic algebra. If you are interested, see Dr. Buckner to sign up for the class. It may be planetary but much of the material is also applicable for stellar. ASTR 2020 Problems in Stellar is a spring class.
