General ⇒ Errors in latex.

[Sam]

Dear All,

I dont know why Latex do not like this equation

\begin{equation}
%\labe{x}
\phi = \atan((X_0 + X)/Y)
\end{equation}

and report an error Stating: 'Undefined Control Scheme'!!!!

Thanks

Hi Sam,

\atan is undefined. But you could define this operator in your preamble:

Code: Select all

\DeclareMathOperator{\atan}{atan}

This requires the amsmath package.
