Warning Codes and Messages

You can use the warnCodes() function to store the codes of warnings generated by evaluating an expression. This table lists each numeric warning code and its associated message. For an example of storing warning codes, see warnCodes(), here.

Warning code

10000

Operation might introduce false solutions.

When applicable, try using graphical methods to verify the results.

10001

Differentiating an equation may produce a false equation.

10002

Questionable solution

When applicable, try using graphical methods to verify the results.

10003

Questionable accuracy

When applicable, try using graphical methods to verify the results.

10004

Operation might lose solutions.

When applicable, try using graphical methods to verify the results.

10005

cSolve might specify more zeros.

10006

Solve may specify more zeros.

When applicable, try using graphical methods to verify the results.

10007

More solutions may exist. Try specifying appropriate lower and upper bounds and/or a guess.

Examples using solve():

solve(Equation, Var=Guess)|lowBound<Var<upBound
solve(Equation, Var)|lowBound<Var<upBound
solve(Equation, Var=Guess)

When applicable, try using graphical methods to verify the results.
