5.5 Properties of the Definite Integral Rita Korsunsky
Property: Definite Integral of a Constant Function If is a real number, then .
Proof is based on the fact that limit of the sum is equal to sum of the limits.
Simplify
Total area = sum of areas a c b
By the above theorem
Mean Value Theorem for Definite Integrals If is continuous on a closed interval , then there is a number in the open interval such that .
Average Value of a Function If is continuous on a closed interval , then the average value of on is .
Average Value of a Function Yielding the general form:
