closer to getting it running right :cheer: just need to figure out the font size issue.... everything is back to what it used to be before

Just hijacking again, for a job purpose...:hihi:

$\Delta\vec{R}=\vec{R}(\vec{V}+\vec{I}\,)-\vec{R}(\vec{V})$

$\Delta\vec{R}=\vec{R}(\vec{V}+\vec{I})-\vec{R}(\vec{V})$

$f_{\rm c}=-\frac{\vec{R}\cdot\Delta\vec{R}}{\mid\Delta\vec{R}\mid^2}$

$f_{\rm c}=-\frac{\vec{R}\cdot\Delta\vec{R}}{\mid\Delta\vec{R}\mid^2}$

$\vec{V}$

$\vec{V}$

I have just figured out that i have forgotten to tell you how to split equations over multiple lines... oooopsie :)

ok its very simple, for that we need to define a block called split like such:

\begin{split} - start of the block

\end{split} - end of the block

yes, please put in both beginning and end bits of this and don't be lazy

after that you can split ines by using \\

you can also align lines by a symbol by using an ampersand (&) in front of it

\begin{split} \text{These Lines}&-\text{will be aligned}\\ \text{by the}&-\text{dash symbol}\\ &-\text{shazaam}\\ \text{boogie boogie} &- \end{split}

And does align work? I try:

$\begin{split} 2&=1+1 \\ 2&=3+1-2 \\ \end{split}$

well, it doesn't seem to work, have to use split then...

##### Share on other sites

no, only split works... i could enable align if there are any benefits to it, granted i actually have that module on the server... ;)

How come it gets parsed even when I put it inside code tags?

##### Share on other sites

way bb works when it parses... if you do not want it to parse, use the noparse tags

[noparse][/noparse]

this way you can post

$m_{rel}=\frac{m_0}{\sqrt{1-\frac{v^2}{c^2}}}$

which would render as

$m_{rel}=\frac{m_0}{\sqrt{1-\frac{v^2}{c^2}}}$

ooh better yet

$\begin{split}\Delta P &= \frac{v}{c} \times \frac{E}{2c} \\ 2\Delta P &= v\frac{E}{c^2} \\ P' &= Mv - 2\Delta P = \left(M-\frac{E}{c^2}\right)v \end{split}$

:)

$\begin{split}\Delta P &= \frac{v}{c} \times \frac{E}{2c}\\ 2\Delta P &= v\frac{E}{c^2} \\ P' &= Mv - 2\Delta P = \left(M-\frac{E}{c^2}\right)v \end{split}$

thnx

never remember all these tags :)

Ok the main thread LaTeX Formulas: Math v2.0 is updated to the math tag standard, please refer back to it to start figuring stuff out.... (there are many hours put into it)

$E=Mc^2$

Well actually lower case m denotes mass, thus the equivalence is not really valid, and even negating that, its a special case...

$\begin{split}E^2-(pc)^2&=(m_0c^2)^2\\E^2&=(m_0c^2)^2+(pc)^2\\E&=\sqrt{(m_0c^2)^2+(pc)^2}\\E&=c\times\sqrt{(m_0c)^2+p^2}\\\text{where } p=\gamma m_0v\\E&=c\times\sqrt{m_0^2c^2+\gamma ^2m_0^2v^2}\\E&=m_0c\times\sqrt{c^2+\gamma v^2}\end{split}$

Okay so the latex seems to have taken a low blow during the site modifications.
