# Math Help - Why isn't this working?

1. ## Why isn't this working?

From this post:

[TEX]m_1 = \sigma \sqrt{\frac{\pi}{2}}[\TEX], or [TEX]\sigma = m_1 \sqrt{\frac{2}{\pi}}[\TEX]

2. ## Re: Why isn't this working?

tex should be in lower case, and end tex should be /tex instead of \tex....

Edit: Ok, this is weird, it works on places outside of the forum, but not on the forum....well, it's working for me now. (reason is in original text)

3. ## Re: Why isn't this working?

Oops -- thanks! Looks like the \ kills it, but for me it doesn't seem to care about case of "tex" tags.
