Name is not a function or program ti 89 error

An argument must be in a specified domain. For example, rand 0 is not valid. The first argument of nSolve must be an equation in a single variable.

It cannot contain a non-valued variable other than the variable of interest. Either the previous calculation did not create Ans, or no previous calculation was entered. This is to avoid confusion between implied multiplication and function calls. A number of commands are not valid outside a function or program.

For example, Local cannot be used unless it is in a function or program. A transmission between two units was not completed. Verify that the connecting cable is connected firmly to both ends. A program reference inside another program could not be found in the provided path during execution. The expression or equation contains an excessive number of arguments and cannot be evaluated. Unsupported function. This function requires Computer Algebra System.

Unsupported operator. This operator requires Computer Algebra System. Unsupported feature. Input argument must be numeric. Only inputs containing numeric values are allowed. The first argument must be a polynomial expression in the second argument. If the second argument is omitted, the software attempts to select a default. The first two arguments must be polynomial expressions in the third argument.

If the third argument is omitted, the software attempts to select a default. Trigonometric conversion operators are not supported in Degree or Gradian angle modes. The first argument of nfMin or nfMax must be an expression in a single variable. Error code. A function did not return a value. Argument cannot be a folder name. Argument mismatch Two or more arguments must be of the same type.

Argument must be a Boolean expression or integer. Argument must be a decimal number. Argument must be a list. Argument must be a matrix. Argument must be a string. Argument must be a variable name. Argument must be an expression. Batteries too low for sending or receiving Install new batteries before sending or receiving. Bound The lower bound must be less than the upper bound to define the search interval. Break The d or c key was pressed during a long calculation or during program execution.

Circular definition This message is displayed to avoid running out of memory during infinite replacement of variable values during simplification. Invalid Data type An argument is of the wrong data type. Dependent limit. Dimension A list or matrix index is not valid. Dimension Error.

Not enough elements in the lists. Dimension mismatch Two or more arguments must be of the same dimension. Domain error An argument must be in a specified domain. Please avoid choosing variable names like x,y,z,a,b,c, These common variable names are frequently used and could easily be included as an argument in a function or program call. Instead, choose variable names like xx, xtemp, yy, ytemp, zz, Then use x,y,z,a,b,c, This minimizes any chance that the function or program called has an argument name that could produce an unexpected result.

For example, simplifying f g x with defined functions f x and g x to see the composition of f composed on g. When the functions f xx and g yy are defined, the simplification of f g x will then give expected results. Composition of functions is also commonly studied when graphing y2 y1 x.

Because the graphing application on these calculators is completely numeric, all composition of functions in graphing work as expected.

However, the graphing functions y1 x ,y2 x , Therefore, if these system graphing functions are used to study composition of functions symbolically on the home screen, unexpected results can occur. A software change was made to detect function and program calls that have expressions of symbolic variable argument names that are the same as those used to define the function or program.

If an error Circular definition is given then it has the newer software. All rights reserved. Add a comment. Active Oldest Votes. Sign up or log in Sign up using Google. Sign up using Facebook.
