INTEGRATION CALCULATIONS
Press to enter COMP mode for integration calculation.
To perform an integration calculation you are required to input
following elements:
• The integration expression has variable x.
• "a" and "b" defining the integration range of the definite integral.
• "n" is the number of partitions (equivalent to N = 2 n ).
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 for performing a
calculation, The calculation precision may be low. Particularly
when significant digits are less than 1, an ERROR might be
occurred.
Example: Perform the integration calculation for
, with n = 4.
! The number of partitions (n) have to specify in the range of 1 to 9
integer, any value that out of the setup division range (N=2 n , n 0,
n=1~9 integer), [Arg ERROR] will be displayed.
! You can skip the number of partitions and the calculator will
automatically assign an appropriate value on behalf of you.
! The smaller the value of n is, the shorter the calculation time is, but
the result is comparatively less accurate; on the other hand, the
bigger the n is, the longer the calculation time is, and the result is
more accurate.
! When performing integration calculation with trigonometric
function, select radian (Rad) as the angle unit setting.
! Log
a
b, i–Rand, Rec ( and Pol ( functions can’t join to integration
calculation.
! During the busy calculation, the calculator will display the message
[PROCESSING].
