## Math 121 - Chapter 7 Study Guide

1. Evaluate the integral. Four parts. Look at problems 7.2.13-30*
2. Evaluate the integrals by making appropriate substitutions. Three parts. Look at problems 7.3.5-36*
3. Write the expression in sigma notation, but do not evaluate. Two parts. Look at problems 7.4.3-12*
4. Express the sum in closed form. Two parts. Look at problems 7.4.23-28*
5. Identify the true identities. Sixteen parts. Look at problems 7.4.49-50, but also any properties of summation and integration throughout the chapter.
6. Sketch the region whose signed area is represented by the definite integral, and evaluate the integral using an appropriate formula from geometry, where needed. Look at problems 7.5.17-20*
7. Evaluate the integrals using the first fundamental theorem of calculus. Three parts. Look at problems 7.6.9-24*
8. Use the second fundamental theorem of calculus to find the derivative. Look at problems 7.6.45-50*
