Integration Calculations

Press to enter COMP mode.

To perform an integration calculation you are required to input the

following elements:

integration expression a b n

• The integration expression has a variable x.

• "a" and "b" defines the integration range of the definite integral.

• "n" is the number of partitions (equivalent to N = 2

The integration calculation is based on Simpson’s rule.

As the number of significant digits is increased, internal integration

calculations may take considerable time to complete. For some

cases, even after considerable time is spent performing a

calculation, the calculation results may be erroneous. Particularly

when significant digits are less than 1, an ERROR might occur.

Example: Perform the integration calculation for, with n = 4.

! You can leave out the x in the differential expression and the

calculator will automatically substitute a value for x.

! The smaller the entered value x is, the the longer the calculation

time will be with more accurate results, the larger the entered value

x is, the shorter the calculation time will be with comparatively

less accurate results.

! Discontinuous points and extreme changes in the value of x can

cause inaccurate results or errors.

! When performing differential calculations with trigonometric

functions, select radian (Rad) as the angle unit setting.

! Log

b, i~Rand, Rec ( and Pol ( functions can not join to differential

calculations.
