• In the function , only X can be used as a variable in expressions. Other
variables (A through Z, r, θ ) are treated as constants, and the value currently
assigned to that variable is applied during the calculation.

• Input of and the closing parenthesis following the precision value can be
omitted.
• Discontinuous points or sections with drastic fluctuation can adversely affect
precision or even cause an error.
• Note that you cannot use a Solve, differential, quadratic differential, integration,
maximum/minimum value or Σ calculation expression inside of a maximum/
minimum calculation term.
• Inputting a larger value for
also increases the amount of time required to perform the calculation.

• You can input an integer in the range of 1 to 9 for the value of
