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, Solve, RndFix or log ab 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.
