u Quadratic Differential Applications
•Arithmetic operations can be performed using two quadratic differentials.
Therefore:
f ''(a) + g''(a), f ''(a) × g''(a), etc.
The result of a quadratic differential calculation can be used in a subsequent arithmetic
or function calculation.
2 × f ''(a), log ( f ''(a) ), etc.
Functions can be used within the terms ( f(x), a, tol ) of a quadratic differential expression.

#You cannot use a differential, quadratic
differential, integration, Σ, maximum/minimum
value or Solve calculation expression inside of
a quadratic differential calculation term.
# Specify tolerance (tol) value of 1
E-14 or less.
An error (Iteration ERROR) occurs whenever
no solution that satisfies the tolerance value
can be obtained.
#You can interrupt an ongoing quadratic
differential calculation by pressing the A key.
#Always use radians (Rad Mode) as the angle
unit when performing trigonometric quadratic
differentials.
