• You can omit input of ∆
automatically substitutes an appropriate value for ∆
you do not input one.
• Discontinuous points and extreme changes in the value
of x can cause inaccurate results and errors.
• Select Rad (Radian) for the angle unit setting when
performing trigonometric function differential calculations.

COMP ............................................................
• The following four inputs are required for integration
calculations: a function with the variable
define the integration range of the definite integral; and
n
, which is the number of partitions (equivalent to N =
n
2 ) for integration using Simpson's rule.
• Example:
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.
• Select Rad (Radian) for the angle unit setting when
