u Applications of Differential Calculations
• Differentials can be added, subtracted, multiplied or divided with each other.
d
––– f (a) = f '(a), ––– g (a) = g'(a)
dx
Therefore:
f '(a) + g'(a), f '(a) g'(a), etc.
• Differential results can be used in addition, subtraction, multiplication, and division, and in
functions.
2 f '(a), log ( f '(a)), etc.
• Functions can be used in any of the terms (
