#In the function f(x), only X can be used as a
variable in expressions. Other variables (A through Z excluding X, r, θ) are treated as
constants, and the value currently assigned to that variable is applied during the calculation.
#Input of n and the closing parenthesis can be omitted.
#Discontinuous points or sections with drastic fluctuation can adversely affect precision or even cause an error.
#You cannot use a differential, quadratic differential, integration, Σ, maximum/minimum
value, Solve, RndFix or log ab calculation expression inside of a maximum/minimum calculation term.
#Inputting a larger value for n increases the precision of the calculation, but it also increases the amount of time required to perform the calculation.
#The value you input for the end point of the interval (b) must be greater than the value you input for the start point (a). Otherwise an error occurs.
#You can interrupt an ongoing maximum/ minimum calculation by pressing the A key.
#You can input an integer in the range of 1 to 9 for the value of n. Using any value outside this range causes an error.
