Integration Calculation Precautions
• In the function
f
(
x
), only X can be used as a variable in expressions. Other variables (A
through Z excluding X,
r
,
Ƨ
) are treated as constants, and the value currently assigned to
that variable is applied during the calculation.
• Input of “
tol
” and closing parenthesis can be omitted. If you omit “
tol
,” the calculator
automatically uses a default value of 1
E
–5.
• Integration calculations can take a long time to complete.
• You cannot use a differential, quadratic differential, integration,
3
, maximum/minimum value,
Solve, RndFix or log
a
b calculation expression inside of an integration calculation term.
• In the Math input/output mode, the tolerance value is fixed at 1
E
–5 and cannot be changed.

Calculation Precautions
• The value of the specified variable changes during a
3
calculation. Be sure to keep separate
written records of the specified variable values you might need later before you perform the
calculation.
• You can use only one variable in the function for input sequence
a
k
.
• Input integers only for the initial term (
A
) of sequence
a
k
and last term (
B
) of sequence
a
k
.
• Input of
n
and the closing parentheses can be omitted. If you omit
n
, the calculator
automatically uses
n
= 1.
• Make sure that the value used as the final term
B
is greater than the value used as the initial
term
A
. Otherwise, an error will occur.
• To interrupt an ongoing
3
calculation (indicated when the cursor is not on the display), press
the
key.
• You cannot use a differential, quadratic differential, integration,
3
, maximum/minimum value,
Solve, RndFix or log
a
b calculation expression inside of a
3
calculation term.
• In the Math input/output mode, the distance between partitions (
n
) is fixed at 1 and cannot be
changed.
