! You can leave out the ax in the differential expression and the
calculator will automatically substitute a value for ax
! The smaller the entered value ax is, the longer the calculation time
will be with more accurate results, the larger the entered value
ax 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 cannot join to differential
calculations.

To perform an integration calculation you are required to input the
following elements:

. The integration expression has the variable x.
. "a" and "b" defines the integration range of the definite integral.
. "n" is the number of partitions (equivalent to N = 2n).
I
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.

Before starting matrix calculations, you have to create one matrix
or a maximum of four matrices named A. B. C and D at one time.
The matrix dimension can be uo to 4x4.

The mahix calculation results are stored into the MatAns memory
automatically. You can use the matrix MatAns memory for any
subseouent matrix calculations.

! Matrices which will be added, subtracted, or multiplied must be the
same size. An error occurs if you try to add, subtract, or multiply
matrices whose dimensions are different from each other. For
example, you cannot add or subtract a 2 x 3 to or from a 2 x2
