Accidently I found a free editor called "TexWriter" in Microsofts's Store. I don't do any form of tex, but this may be of interest to those posting in this thread.

BTW I see someone has added "fuel" to words under my avatar - Thanks. It still looks like there is space to make it read either:
"Help me! Please use sugar cane alcohol fuel."
Or if that will not fit, just:
"Help me! Use sugar cane alcohol fuel."

Now you know what is wrong with being helpful and kind: They always want more; but I promise that is not true in this case.

$\frac{1}{\frac{1}{0}}=0$

Great cut and paste I made from last month that still wont show up properly.

$\lim_{x\to 1} \, (x+1)$

$\lim _{x\rightarrow 1}{x}^{17}-x+3$

What's the problem? If it's the limit, you can use the \displaystyle command to make it appear under the "lim":

$\displaystyle \lim_{n \rightarrow \infty} \, \Bigl( 1 + \frac{x}{n} \Bigr)^{n} = e^{x} \,.$​

Look at the post below rpenner's response http://www.sciforums.com/members/beer-w-straw.62513/

It's this: $\frac{1}{\frac{1}{0}}=0$

Testing - ignore this.

$F(\theta ,\phi ,r)=R(r)f(\theta,\phi)$

$F(\theta ,\phi ,r)=R(r)(2\phi +\theta )$

Test:

\begin{bmatrix}\gamma & -\beta_x\gamma & 0 & 0\\
-\beta_x\gamma & \gamma & 0 & 0\\
0 & 0 & 1 & 0\\
0 & 0 & 0 & 1
\end{bmatrix}
The question now is: How to get the above left aligned ? Cannot get {flushleft} to work

Post it inline with [ tex ] ?

$\begin{bmatrix}\gamma & -\beta_x\gamma & 0 & 0\\ -\beta_x\gamma & \gamma & 0 & 0\\ 0 & 0 & 1 & 0\\ 0 & 0 & 0 & 1 \end{bmatrix}$

Thanks, but please explain in more detail because I do not know what you mean by this or how to do what you are saying.
All I can do is look at the Tex commands you are using and they are identical to the ones I used.

but they are wrapped in [ tex ] [/ tex ] markers.

Test 2:
Front text - $\begin{bmatrix}\gamma & -\beta_x\gamma & 0 & 0\\ -\beta_x\gamma & \gamma & 0 & 0\\ 0 & 0 & 1 & 0\\ 0 & 0 & 0 & 1 \end{bmatrix}$ - Middle text - $\begin{bmatrix}\gamma & -\beta_x\gamma & 0 & 0\\ -\beta_x\gamma & \gamma & 0 & 0\\ 0 & 0 & 1 & 0\\ 0 & 0 & 0 & 1 \end{bmatrix}$ - Back text

So that was:

Front text - [ tex ]
<tex stuff>
[/ tex] - Middle text - [ tex ]
<tex stuff>
[/ tex] - Back text

Test 2 passed

Thanks.
