u Applications of Differential Calculations
• Differentials can be added, subtracted, multiplied and 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.
