k k k k k Applications of Differential Calculations
• Differentials can be added, subtracted, multiplied and divided with each other.
d
––– f (a) = f '(a), ––– g (a) = g'(a)
Example
dx
Therefore:
f '(a) + g'(a), f '(a) ( g'(a)
• 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 (
d
Example ––– (sin
dx
• Note that you cannot use a Solve, differential, quadratic differential, integration,
maximum/minimum value or ! 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.
