20070201u Applications of Differential Calculations• Differentials can be added, subtracted, multiplied or divided with each other.Therefore:f ' (a) + g' (a), f ' (a) × g' (a), etc.• Differential results can be used in addition, subtraction, multiplication, and division, and infunctions.2 × f ' (a), log ( f ' (a)), etc.• Functions can be used in any of the terms (f ( x), a, tol) of a differential.d d––– f (a) = f '(a), ––– g (a) = g'(a)dx dxd d––– f (a) = f '(a), ––– g (a) = g'(a)dx dxd––– (sinx + cosx, sin0.5, 1 E - 8), etc.dxd––– (sinx + cosx, sin0.5, 1 E - 8), etc.dx2-5-4Numerical Calculations# You cannot use a differential, quadraticdifferential, integration, Σ, maximum/minimumvalue, Solve, RndFix or log ab calculationexpression inside a differential calculationterm.# 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 angleunit when performing trigonometric differentials.
