How to align the math formula to left?
I want to let and Ttotal and Teach tile has the same x-coordinate.

There are my code about two math formula as below:

\subsection{Cost Time}
The comparison of cost time of QVSM and Smart Shadow Maps Refinement is show in (Figure \ref{fig:7-costime}). If the red region is the effective shadow region and do not need split into 2x2 subtiles further.
QVSM:\\
$T_{total} = T_{eye} + T_{sm} + T_{SRT} + 4 \times T_{each tile}+ 4 \times 4 \times T_{each tile}$\\
$T_{each tile} = T_{sm} + T_{SRT}$\\

Hi,

you could use amsmath and align, if you want to align to the relation symbol:

Code: Select all

1
2

QVSM:
\begin{align*}
T_{total} &= T_{eye} + T_{sm} + T_{SRT} + 4 \times T_{each tile}+ 4 \times 4 \times T_{each tile }\\
T_{each tile} &= T_{sm} + T_{SRT}
\end{align*}

If you want it left aligned instead, tell us.

You are loading the amsmath package twice. Once with and once without the fleqn option.

I have an align* that's behaving very badly -- there's a huge space after the second ampersand -- any help would be much appreciated.

This is what it renders like (using fullpage[cm])

Just delete the second ampersand. It's useless in this case.
