# How to use greek letters in \text environment inside math?

I tried something like $(\lambda x. x\ x)(\lambda x. x\ x) \text{cannot be \beta-reduced to something else}$. How can I make TeX output a real beta where I want?

I found out how to do it by myself. I just had to encapsulate the \beta into dollar signs again: $(\lambda x. x\ x)(\lambda x. x\ x) \text{cannot be$\beta$-reduced to something else}$
• While your answer is technically correct, I'd say it is basically wrong. The right answer is $(\lambda x. x\ x)(\lambda x. x\ x)$ cannot be $\beta$-reduced …. More generally, \text is very rarely appropriate in inline math. Display math is another story altogether. – Harald Hanche-Olsen Apr 2 '11 at 14:19
• If you are using MathJax with HTML, why not just type the HTML entity? &beta;-reduced produces "β-reduced" – Willie Wong Apr 3 '11 at 0:22
