This program covers the important topic of Trigonometric Integrals in Calculus. We begin by discussing what Trigonometric Integrals are and why it is a central topic in Calculus. Next, we solve several practical calculus problems that give students practice with Trigonometric Integrals. 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.
