Press to access the numerical integration option which approximates the definite integral of an expression with respect to a variable from a start value to an end value.



Next, enter an expression, the variable, a start value, and an end value separated by commas. For example, to find the antiderivative of x3 evaluated from x = 1 to x = 2, enter

3 1 2
