(1) Positive Part
(2) Negative Part
When integration values fluctuate widely due to minute shifts in the
integration interval
Divide the integration interval into multiple parts (in a way that breaks
areas of wide fluctuation into small parts), perform integration on each
part, and then combine the results.
Differential Calculations
Function for approximation of the derivative based on the central
difference method.
Natural Display input syntax is
d
dx
(f (x)) |
x=a
, while Linear Display input
syntax is
d
dx
(f (x); a; tol).
tol specifies tolerance, which becomes 1 × 10
-10
when nothing is input for
tol.
