    Just a test for LaTeX on this forum.

    Hi

    This is only for my own use to make sure my LaTeX comes out right.

    I don't want to make a mess of any maths layout I submit in my posts.

    \frac{dy}{dx}(2x^2+6) = 4x

    Regards

    Test Post :

    \frac{dy}{dx}(2x^2+6) = 4x \\ \log_{5} 25=2

    \sqrt[3]{2}

    \arctan 45

    \sum x_i

     178 \pm 5

    this  \Leftrightarrow \\  this



      \begin{array}{l|cr|}4&1&2\\-4&-1&-2\\\hline\end{array}

    f(x)=\left\{\begin{array}{cc}0,&\mbox{ if }x\leq 0\\1, & \mbox{ if } x>0\end{array}\right.

      \left(\begin{array}{cc}1&9\\7&1\end{array}\right)

      \begin{array}{cc}1&0\\0&1\end{array}


      \begin{array}{lcr}4&1&2\\-4&-1&-2 \\-4&-1&-2 \end{array}

    Hello, guinster!

    You're doing great!


    Personally I dislike those long minus-signs.

    To me, \begin{pmatrix} 3 & -1 \\ -2 & 0 \end{pmatrix} looks awkward.

    I prefer: . \begin{pmatrix}3 & \text{-}1 \\ \text{-}2 & 0 \end{pmatrix}

    where I replace - with \text{-}.

    Thanks from topsquark and guinster

    If you put \phantom{-} before the positive terms they end up lined up properly

    Re: Just a test for LaTeX on this forum.

    Also it's common practice to write the d's in a different font when they're used for differentials.

    \frac{\mathrm{d}y}{\mathrm{d}x} gives $\displaystyle \begin{align*} \frac{\mathrm{d}y}{\mathrm{d}x} \end{align*}$

    In fact, the mathrm font is used when your letter is used for something other than a variable, such as a predefined constant like $\displaystyle \begin{align*} \mathrm{e} \end{align*}$ or $\displaystyle \begin{align*} \mathrm{i} \end{align*}$ as well

    Thanks Prove It

    Those differentials look 'the business'.

    Cheers
