AREA
(
Fn
, [
Fm
,]
lower, upper
)
Example:
AREA
(-
X
,
X
2
-2, -2, 1) returns 4.5
EXTREMUM
Extremum of a function. Finds the extremum (if one exists)
of the function Fn that is closest to the
X
-value guess.
EXTREMUM
(
Fn, guess
)
Example:
EXTREMUM
(
X
2
-
X
-2, 0) returns 0.5
ISECT
Intersection of two functions. Finds the intersection (if one
exists) of the two functions Fn and Fm that is closest to the
X
-value guess.
ISECT
(
Fn, Fm, guess
)
Example:
ISECT
(X, 3-
X
,2) returns 1.5
ROOT
Root of a function. Finds the root of the function Fn (if one
exists) that is closest to the
X
-value guess.
ROOT
(
Fn, guess
)
Example:
ROOT
(3-
X
2
, 2) returns 1.732…
SLOPE
Slope of a function. Returns the slope of the function Fn
at the
X
-value (if value exists).
SLOPE
(
Fn, value
)
Example:
SLOPE
(3-
X
2
, 2) returns -4
Solve app
functions
The Solve app has a single function that solves a given
equation or expression for one of its variables.
En
may be
an equation or expression, or it may be the name of one
of the Solve Symbolic variables E0-E9.
SOLVE
Solve. Solves an equation for one of its variables. Solves
the equation
En
for the variable
var
, using the value of
guess
as the initial value for the value of the variable
var
.
If
En
is an expression, then the value of the variable
var
that makes the expression equal to zero is returned.
