Note: For a complete
description of each function
and its syntax, refer to
Appendix A.
Note: The d symbol for
differentiate is a special
symbol. It is not the same as
typing the letter D on the
keyboard. Use ... 1 or
2 = .
You can use the ... Calc toolbar menu to select commonly
used calculus functions.
From the Home screen, press ... to display:
Menu Item Description
Differentiates an expression with respect to a
d differentiate
specified variable.
‰ integrate Integrates an expression with respect to a specified
variable.
limit Calculates the limit of an expression with respect to
a specified variable.
G sum Evaluates an expression at discrete variable values
within a range and then calculates the sum.
Evaluates an expression at discrete variable values
product
within a range and then calculates the product.
Finds candidate values of a specified variable that
fMin
minimize an expression.
Finds candidate values of a specified variable that
fMax
maximize an expression.
Returns the arc length of an expression with respect
arcLen
to a specified variable.
Calculates a Taylor polynomial approximation to an
taylor
expression with respect to a specified variable.
nDeriv Calculates the numerical derivative of an expression
with respect to a specified variable.
nInt Calculates an integral as a floating-point number
using quadrature (an approximation using weighted
sums of integrand values).
Symbolically solves many 1st and 2nd order
