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

––– 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.

on the display) interrupts the calculation.
• Always use radians (Rad Mode) as the angle unit when performing trigono-
