•You can omit input of ∆x, if you want. The calculator automatically substitutes an appropriate value for ∆x if you do not input one.
•Discontinuous points and extreme changes in the value of x can cause inaccurate results and errors.
Integration Calculations
COMP
The procedure described below obtains the definite integral of a function.
Use the F key to enter the COMP Mode when you want to perform integration calculations.

•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.

Note!
•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.
