For the solve( function, guess must be between lower and
upper.

The guess and several points around it are undefined.
Examine a graph of the function. If the equation has a solution,
change the bounds and/or the initial guess.

You have pressed the É key to break execution of a program,
halt a DRAW instruction, or stop evaluaton of an expression.
You have entered a value or variable that is the wrong data
type.
¦
A function (including implied multiplication) or an
instruction has an argument that is an invalid data type; for
example, a list where a real number is required. See
Appendix A and the appropriate chapter.

In an editor, you have entered a type that is not allowed; for
example, a matrix as an element in the
the appropriate chapter.

You are attempting to store to an incorrect data type; for
example, a matrix to a list.
You are attempting to perform an operation that has more than
one list or matrix, but the dimensions do not match.
