5.4 Worksheet Day 1
All work must be shown in this course for full credit. Unsupported answers may receive NO credit.
For questions 1 10, use the Fundamental Theorem of Calculus (Evaluation Part) to evaluate each definite
integral. Use your memory of derivative rules and/or the chart from your notes. You should start making a list of
all the rules on ONE page!
