How to: use LaTeX for equations

alexander · 05-04-2006

probably could add that to the latex bb tag, to add names automatically, but still, i want it to work the way it is supposed to!

success, this actually finally works, its alive

$f(x)=\sum_{i=1}^5(x^e^{x+i})$

Great job, Alexander!

ok, i think that this thread needs a little pointing, for those who are interested, i just finished a tutorial on Latex in the math section (sort of where its needed a bit more) so please dont hesitate and visit:
LaTeX Fomulas: Math v2.0

there is also a link to latex practice grounds thread, and if you have any questions, please, please post them in the linked stickey, i want people to be able to refer to a single thread for guidance... I dunno whether i should block this thread or something, but please go to the Physics and Math section for the latex stuff...

Really just getting started with this Latex and already I've discovered a problem. I understand how to show sqrt-root but how do I show cube-root or even higher powers of this function? Any help would be appreciated.....Infy

\sqrt[3]{X} renders as $\sqrt[3]{X}$

Though there are many excellent LaTeX references, I usually refer to http://meta.wikimedia.org/wiki/Help:Formula . I don’t think it’s complete, but it’s yet to fail to answer any of my questions.

Excellent, thank you so much my friend.............................Infy

$\sum_q \frac{\partial}{\partial x_q}\vec{\psi} = 0$

Is that correct, or is there a way to have equations display within quotes?

p.p.s.
Thanks for the answer; I never would'a guessed that....

The backslashes get stripped when quoted. Instead of using one backslash, use two - one will be stripped, the other will remain. So, it will look like this:
\sum_q \frac{\partial}{\partial x_q}\vec{\psi} = 0 normally and

\\sum_q \\frac{\\partial}{\\partial x_q}\\vec{\\psi} = 0 in quotes. Also, if you preview your post you'll have to re-double-up the backslashes before submitting.
