Numerical Calculations

uApplications of Differential Calculations

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

d

d

––– f (a) = f '(a),––– g (a) = g'(a)

dx

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.2 f '(a), log ( f '(a)), etc.Functions can be used in any of the terms (f (x), a, tol) of a differential.

d

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

#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.
