Writing Prompts
• Why?
• Explain the meaning of a definite integral in the context of the
problem
• Explain the meaning of a derivative in the context of the problem
What to do?
. . . the short answer
• Determine which theorem or definition applies
• State (show) that your problem meets the
hypotheses of the theorem or definition – BE

Explain the meaning of
. . . a definite integral
Include three things in the context of the problem:
1. What the integral gives (amount, average value,
change in position, etc.)
2. Units
3. What the limits of integration mean.
