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.

To calculate e

log 1000 = 3 l 1000 = 3.

To calculate ln 90 (= log

90) to three significant digits (Sci 3)

N 2(Sci) 3 i 90 = 4.50×10

1.2 × 10

= 120 1.2 * 10 x= 120.
