4.3 Finding Area Under A Curve Using Area Formulas Objective: Understand Riemann sums, evaluate a definite integral using limits and evaluate using properties AP Calculus AB
Riemann Sum
Area under the curve between a and b. The integral is equal to the area under the curve only if the curve lies entirely above the x-axis. Theorem 45 on Pg. 274 Today, we are only using formulas for shapes that we know a b
