This document provides a series of sample questions focused on the technique of substitution in calculus. Specifically, it discusses how to substitute a variable ( u ) into an original equation and apply integration techniques, such as increasing the power by one and dividing by the new power. Key concepts like derivatives and specific substitution examples, such as letting ( u = 1 + 2x ), are included to help reinforce these integration methods. Ideal for students looking to enhance their understanding of polynomial integration.
