• 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. COMP F 1 • 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. d expression P a P b P n F • Example: ∫ 5 (2x2 + 3x + 8) dx = 150.6666667 1 (Number of partitions n = 6) d 2 p x K + 3 p x + 8 P 1 P 5 P 6 T = 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.
