Lesson 27: Integration by Substitution (worksheet solutions)

1) The document provides solutions to 12 integrals using substitution techniques. Substitutions included letting u = functions of x and using trigonometric identities. 2) Integrals were evaluated as both definite integrals, giving numbers, and indefinite integrals, giving general antiderivatives. 3) Multiple methods were sometimes shown, such as using long division or direct substitution to solve one integral.
