u Applications of Differential Calculations

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

Therefore:

•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 ( f (x), a, tol) of a differential.

Numerical Calculations

#You cannot use a differential, quadratic

differential, integration, Σ, maximum/minimum

value or solve calculation expression inside a

differential calculation term.

#Pressing A during calculation of a differential

(while the cursor is not shown on the display)

interrupts the calculation.

#Always use radians (Rad Mode) as the angle

unit when performing trigonometric differentials.

––– f (a) = f '(a), ––– g (a) = g'(a)

dx dx

f '(a) + g'(a), f '(a) × g'(a), etc.

––– (sinx + cosx, sin0.5, 1E - 8), etc.
