Riemann Sum We start by subdividing the interval [a, b] into n subintervals The width of the interval [a, b] is b-a the width of each subinterval is The subintervals are

Sec 5. 3 The Definite Integral

The Definite Integral Definition: the definite integral of ƒ over [a, b] Example: Find the definite integral of ƒ(x) = x + 2 over [ -1, 1 ] Remark: Definition: the definite integral of ƒ over [a, b]

Partition is called a partition of [a, b]. Note that the length of subintervals are not the same Example Is a partition of [0, 10]. Is a partition of [0, 9]. Is a partition of [0, 10].

Partition subinterval widths Example Def: Norm of the partition the largest of all the subinterval widths Is a partition of [0, 10]. Example

Riemann Sum Riemann sum for ƒ on the interval [a, b]. Example: Find the Riemann sum for ƒ(x) = x + 2 over [ 0, 5 ]
