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.

 

SOLVE(En,var,guess)

 

Example:

 

SOLVE(X2-X-2,X,3)returns2

 

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

 

3—neither a solution, an approximation, nor an

 

extremum was found

 

See chapter 13, “Solve app”, beginning on page 259, for

 

more information about the types of solutions returned by this

 

function.

Spreadsheet app functions

The spreadsheet app functions can be selected from the App

Toolbox menu: press D, tap and select Spreadsheet. They can also be selected from the View menu (V) when the Spreadsheet app is open.
