Σ Σ Calculation Precautions
• The value of the specified variable changes during a Σ 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
• Input integers only for the initial term ( α ) of sequence
n
• Input of and the closing parentheses can be omitted. If you omit
automatically uses
• Make sure that the value used as the final term β is greater than the value used as the initial
term α . Otherwise, an error will occur.
• To interrupt an ongoing Σ calculation (indicated when the cursor is not on the display), press
the A key.
• You cannot use a differential, quadratic differential, integration, Σ , maximum/minimum value,
Solve, RndFix or log
k Maximum/Minimum Value Calculations
After displaying the function analysis menu, you can input maximum/minimum calculations
using the formats below, and solve for the maximum and minimum of a function within interval
a < x < b
.
