Examples
Example 1
∫ x^2 dx from 0 to 1
Result = 0.33333333
Example 2
∫ sin(x) dx from 0 to π
Result = 2 in radian mode
Example 3
∫ (3x + 2) dx from 0 to 5
Result = 47.5
Estimate a definite integral numerically with Simpson's rule. It is useful for quick checks and school work when you do not need a symbolic answer.
