## Course Description

After studying the integral from calculus 1 and having seen some integral applications in calculus 2, we are now ready for an in-depth look at integration techniques. We begin this course with one of the most commonly used techniques, integration by parts. In the first lesson, we derive the formula and work through several examples of using it and when to use it.

In the next lesson, we cover trigonometric integrals. These are integrals that involve the product of trigonometric functions. In particular, the product of powers of sines and powers of cosines are detailed. Guidelines for several other forms are also detailed.

After understanding trigonometric integrals, we can now look for those integral substitutions that yield a trigonometric integral. We classify several types of substitutions here in this lesson and demonstrate how to use each one.

The method of partial fractions is explored next. We break this technique down into four cases: namely, distinct linear factors, repeated linear factors, distinct irreducible quadratic factors, and repeated irreducible quadratic factors. Each case is thoroughly discussed.

After partial fractions, we study improper integrals. We examine both infinite intervals of integration and improper integrals with infinite discontinuities. We end this fun course with a comparison test for improper integrals.
