Integration Calculations
• The following four inputs are required for integration cal-
culations: 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
=
2
n
)
for integration using Simpson’s rule.

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, of you want.
•Internal integration calculations may take considerable
time to complete.
•Display contents are cleared while an integration calcu-
lation is being performed internally.
Degrees, Minutes, Seconds
Calculations
•You can perform sexagesimal calculations using degrees
(hours), minutes, and seconds, and convert between
sexagesimal and decimal values.
• Example 1: To convert the decimal value 2.258 to a
sexagesimal value
2.258
=
