ISECT(Fn,Fm,guess)
Example:
ISECT(X,3-X,2) returns 1.5
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:
,2) returns 1.732...
2
ROOT(3-X
Slope of a function. Returns the slope of the function Fn at the
X-value (if value exists).
SLOPE(Fn,value)
Example:
,2) returns -4
2
SLOPE(3-X
The Solve app has a single function that solves a given
equation or expression for one of its . En may be an equation
or expression, or it may be the name of one of the Solve
Symbolic E0-E9.
Solve. Solves an equation for one of its . 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.
SOLVE(En,var,guess)
Example:
2
SOLVE(X
-X-2,X,3)returns 2
This function also returns an integer that is indicative of the
type of solution found, as follows:
0—an exact solution was found
1—an approximate solution was found
2—an extremum was found that is as close to a solution
as possible
