k Applications of Differential Calculations

• Differentials can be added, subtracted, multiplied and divided with each other.

Example

• Differential results can be used in addition, subtraction, multiplication, and divi-

sion, and in functions.

Example 2 × f '(a), log ( f '(a))

• Functions can be used in any of the terms ( f (x), a, ∆x) of a differential.

Example

• Note that you cannot use a Solve, differential, quadratic differential, integration,

maximum/minimum value or Σ calculation expression inside of a differential cal-

culation term.

• Pressing A during calculation of a differential (while the cursor is not shown

on the display) interrupts the calculation.

• Always perform trigonometric differentials using radians (Rad Mode) as the

angle unit.

––– f (a) = f '(a), ––– g (a) = g'(a)

Therefore:

f '(a) + g'(a), f '(a) × g'(a)
