## Introducing LaTeX Math Typesetting

 Originally posted by Hurkyl One should probably use $\mathbb{N}/\mathbb{N}$ style fractions in inline text anyways, but a bug is still a bug!
I agree with Hurkyl. fraction type $\frac{\mathbb{N}}{\mathbb{N}}=\mathbb{N}$ should only be used in equation ( or eqnarray), but while writing along with text we should use $\mathbb{N}/\mathbb{N}$

 any ideas why this isn t working? $$\begin{multline*} \tan^n \theta=\tan^{n-2}\theta \tan^2 \theta\\ =\tan^{n-2}\theta(\sec^2\theta-1)=\tan^{n-2}\theta\sec^2\theta-\tan^{n-2}\theta \end{multline*}$$

Try this: $$\begin{multline*} \tan^n \theta=\tan^{n-2}\theta \tan^2 \theta\\ =\tan^{n-2}\theta(\sec^2\theta-1)=\tan^{n-2}\theta\sec^2\theta-\tan^{n-2}\theta \end{multline*}$$ - Warren

oops... i m an idiot.

thanks chroot.

 $$\mathcal{P}(X)$$
 Hi folks! I'm just setting up a practice spot for myself here. Don't mind me. These will be changing/dissappearing as I get new thoughts, but feel free to watch my struggles. $$M^2 = \left( \begin{array}{cc} M^2_{11} & M^2_{18}\\ M^2_{18} & M^2_{88} \end{array} \right)$$ $$M^2_{88} = \frac {1}{3} \left(4m^2_{K} - m^2_{\pi}\right)$$ $$M^2_{11} = m^2_{\eta} + m^2_{\eta'} - M^2_{88}$$ $$M^2_{18} = - \sqrt{(M^2_{88} - m^2_{\eta})(m^2_{\eta'} - M^2_{88})}$$ $$\tan\theta_{P} = \frac {M^2_{88} - m^2_{\eta}}{M^2_{18}}$$ Dang this is freakin' cool!!! $$\begin{multline*} \eta = \eta_{8}\cos\theta_{P} - \eta_{1}\sin\theta_{P}\\ \eta' = \eta_{8}\sin\theta_{p} + \eta_{1}\cos\theta_{P} \end{multline*}$$ $$\eta_{1} = \frac {u\bar{u} + d\bar{d} + s\bar{s}}{\sqrt{3}}, \eta_{8} = \frac {u\bar{u} + d\bar{d} - 2s\bar{s}}{\sqrt{6}}$$ I just can't stop... $$\nu_e$$ $$\nu_e\bar$$
 Recognitions: Gold Member Science Advisor $$\neq$$ What would be the symbol for 'not equivalent to' and how would you represent it in latex?
 Recognitions: Gold Member Science Advisor Wouldn't it just be a crossed equivalent sign (or is that stronger than 'not equivalent to'?)? which I can't seem to get that anyway. $$\nequiv \notequiv$$
 $$\not\equiv$$
 Recognitions: Gold Member Science Advisor thanks! I was looking at a table of glyphs used in maths and it had that sign as 'not identical to' is that interchangable with 'not equivalent to' or can the sign mena both things?
 The symbol can be read as either "identical" or "equivalent".

By the way, I never answered this...

 Originally posted by chroot Can you tell me why the font size is different between these two images? $\int_{a}^{b}} e^x dx$ $e^x = \sum_{n=0}^\infty \frac{x^n}{n!} = \lim_{n\rightarrow\infty} (1+x/n)^n$
Look at the TeX for the first one: it has an extra closing curly brace }. Thus, since the TeX expression is being implicitly enclosed within \inline{...}, that extra brace closes the inline, and the e^x dx is not inlined.

You don't need the curly braces here anyway... it should just be $\int_a^b e^x\,dx$.
 Wow this is awesome, but is there a sperate program or way that I can do the Math Typesetting offline or find it as a standard software? I would like to be able to type out some mathematical notes for my self since my hand writing is a bit sloppy and my notebook becomes incoherent... [g)]

You can use MiKTeX if you use Windows. If you use Linux, your distro should already have TeX and LaTeX software.
 im kinda slow, andim not that advanced, so im tryin lil things. but i like this thing, ima be the only person in my class with a fully typed physics report. $f_{x}=f\cos\theta$

I installed it but how do I use it? Do I just go to notepad and type up and save it as a .dvi file?
