Differential Calculation Precautions
Differential calculation can be performed in the COMP Mode only.
The following cannot be used in f(x): Pol, Rec, ÷R. The following cannot
be used in f(x), a, b, or tol: , d/dx, Σ, Π.
When using a trigonometric function in f(x), specify Rad as the angle
unit.
A smaller tol
value increases precision, but it also increases calculation
time. When specifying tol, use value that is 1 × 10
-14
or greater.
If convergence to a solution cannot be found when tol input is omitted,
the tol value will be adjusted automatically to determine the solution.
Non-consecutive points, abrupt fluctuation, extremely large or small
points, inflection points, and the inclusion of points that cannot be
dif
ferentiated, or a differential point or differential calculation result that
approaches zero can cause poor precision or error.
Σ Calculations
Function that, for a specified range of f(x), determines sum
(f(x)) = f(a) + f(a + 1) + f(a
+ 2) + + f(b).
Natural Display input syntax is
(f(x)), while Linear Display input syntax
is (f(x), a, b).
a and b are integers that can be specified within the range of -1 × 10
10
< a
b < 1 × 10
10
.
Example:
(x + 1) = 20
