This program covers the important topic of Ratio and Root Tests of Series Convergence in Calculus. We begin by discussing what a Ratio and Root Test is and why it is a central topic in Calculus. Next, we solve several practical calculus problems that give students practice with these calculations. The entire lesson is taught by working example problems beginning with the easier ones and gradually progressing to the harder problems. Emphasis is placed on giving students confidence in their skills by gradual repetition so that the skills learned in this section are committed to long-term memory.
