• In the function f(x), only X can be used as a variable in expressions. Other
variables (A through Z, r, ) are treated as constants, and the value currently
assigned to that variable is applied during the calculation.
• Input of the final boundary value
• Discontinuous points or sections with drastic fluctuation can adversely affect
precision or even cause an error.

• Arithmetic operations can be performed using two quadratic differentials.

––– f (a) = f ''(a), ––– g (a) = g''(a)

Therefore:
f ''(a) + g''(a), f ''(a) g''(a), etc.
• The result of a quadratic differential calculation can be used in a subsequent
arithmetic or function calculation.

• Note that you cannot use a Solve, differential, quadratic differential, integration,
maximum/minimum value or
differential calculation term.
• Use only integers within the range of 1 to 15 for the value of final boundary
Use of a value outside this range produces an error.
• You can interrupt an ongoing quadratic differential calculation by pressing the
A key.
• Always use radians (Rad Mode) as the angle unit when performing trigono-
metric quadratic differentials.
