Integration Calculations

The procedure described below obtains the definite integral of a function.

The following four inputs are required for integration calculations: a function with the variable x; a and b, which define the integration range of the definite integral; and n, which is the number of partitions (equivalent to N = 2n) for integration using Simpson's rule.

expression a b n


Example: ∫51(2x2 + 3x + 8)dx = 150.6666667 (Number of partitions n = 6)

  • 2(X)3(X)
    8156
  • 150.6666667

Note

Integration calculations can be performed in the COMP Mode only.

You can specify an integer in the range of 1 to 9 as the number of partitions, or you can skip input of the number of partitions entirely, if you want.

Internal integration calculations may take considerable time to complete.

Display contents are cleared while an integration calculation is being performed internally.

Select Rad (Radian) for the angle unit setting when performing trigonometric function integration calculations.
