    Hi James,
    Secret had problems with tex in this thread: [thread=136988]Deriving gradient operator in spherical coord using chain rule[/thread]
    przyk noted that adding white space made the problem go away.

    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.

    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
