Appendix B: Technical Reference
The first argument must be an equation, and the equation cannot
contain a non-valued variable other than the variable of interest. For
example, nSolve(3x^2- 4=0, x) is a valid equation; however,
nSolve(3x^2- 4, x) is not an equation, and nSolve(3x^2- y=0,x) is not
a univariate equation because y has no value in this example.
For example, solve(3x^2- 4, x) is invalid because the first argument is
not an equation.
An attempt was made in the VAR-LINK menu to store a variable in a
folder that does not exist.
For example, x(x+1) is invalid; whereas, x
syntax. This is to avoid confusion between implied multiplication and
function calls.
Only certain commands are valid in a user-defined function. Entries
that are made in the Window Editor, Table Editor, Data/Matrix Editor,
and Solver as well as system prompts such as Lower Bound cannot
contain any commands or a colon (:). See also "Creating and
Evaluating User-Defined Functions" in the Calculator Home Screen
module.
Label names must follow the same rules used for naming variables.
For example, a list inside a list such as {2,{3,4}} is not valid.
