I'm trying to write some report in Latex, and I need to use amsmath further in the code, but since I added this package, the following piece of code stopped working (initially it was between \\[\\]
instead of \begin{equation}
and \end{equation}
).
When I run my code, it stops on the following piece:
\begin{equation*}
\text{d\overrightarrow{u} = } L \text{d\overrightarrow{x} with } L =\left( \begin{array}{ccc}
\frac{\partial u_{1}}{\partial u_{1}} & \frac{\partial u_{1}}{\partial u_{2}} & \frac{\partial u_{1}}{\partial u_{3}} \\
\frac{\partial u_{2}}{\partial u_{1}} & \frac{\partial u_{2}}{\partial u_{2}} & \frac{\partial u_{2}}{\partial u_{3}} \\
\frac{\partial u_{3}}{\partial u_{1}} & \frac{\partial u_{3}}{\partial u_{2}} & \frac{\partial u_{3}}{\partial u_{3}} \end{array}\right)
\end{equation*}
With the error:
Missing $ inserted.
<inserted text>
$
l.15 \text{d\overrightarrow{u} = }
L \text{d\overrightarrow{x} with } L =\le..
?
I'd be grateful if I could get any help on this. If I missed a similar post, I'm really sorry for that, I checked around before posting.
Cheers JF
\vec{u}
better than\overrightarrow{u}
?\newcommand*\dd{\mathop{}\!\mathrm{d}}
. Then use\dd\vec{u} = L \dd\vec{x} \text{ with } L = ..
