Integration and Differential Calculation
Precautions
• Integration and differential calculations can be performed in the
COMP Mode (
,1) only.
• When using a trigonometric function in
f
(
x
), specify Rad as the angle
unit.
Precautions for Integration Calculation Only
• 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.
Precautions for Differential Calculation Only
• You can omit input of
Δ
x
, if you want. The calculator automatically
substitutes an appropriate value for
Δ
x
if you do not input one.
• Discontinuous points and extreme changes in the value of
x
can
cause inaccurate results and errors.
