This is a collaborative partner activity covering the radius and interval of convergence of a power series. Students will need to use the ratio and/or the root tests to determine the radius of convergence. Each partner will work on total of 10 problems. Partners’ corresponding problems are similar (problem A1 is similar to problem B1, problem A2 is similar to problem B2 and etc). Thus partners will work on different problems, but will be encouraged to help each other with methods. Recording
