signed to that variable is applied during the calculation.
• Input of the final boundary value
• Discontinuous points or sections with drastic fluctuation can adversely affect pre-
cision 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)
• The result of a quadratic differential calculation can be used in a subsequent
arithmetic or function calculation.

• Functions can be used within the terms (

• Note that you cannot use a Solve, differential, quadratic differential, integration,
maximum/minimum value or ! calculation expression inside of a quadratic differ-
ential 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 Ma ERROR.
• You can interrupt an ongoing quadratic differential calculation by pressing the
A key.
• You should always specify radians (Rad) as the unit of angle unit before per-
forming a quadratic differential calculation using trigonometric functions.
