Calculus
Functions
You will find the symbols for the calculus functions derivative
and integral in the CHARS menu (■ [CHARS]) as well as the
MATH menu.
a
Differentiates
expression
with respect to the
variable
of
differentiation. Use a formal variable (si, etc.) for a non
numeric result.
doariable(expression)
Example: asl (sl^+3*sl) returns 2*sl+3
f
Integrates
expression
from
lower
to
upper
limits with respect to
the
variable
of integration. To find the definite (numeric)
integral, both limits must have numeric values (that is, be
numbers or real variables). To find the indefinite integral, one
of the limits must be a formal variable (si, etc.).

finds the indefinite result 3*sl+2*(sl''2/2)
TAYLOR
Calculates the nth order Taylor’s polynomial of
expression
at the
point where the given
variable
=0.
