# Thread: Introducing myself to the forum.

1. ## Introducing myself to the forum.

I've been studying Rotman, An Introduction to the Theory of Groups, 4th edition. I could not cope with the last two chapters. Too dificult for me. I made three years at the university and left. NOw I have aimed a little lower and I am studying an undergraduate text: George W. Polites, 1968. And have a lot of questions. Also I must familiarize myself with Tex or Latex. How do you enclose math expressions. $expression$? Well I think you'll get to know me better through my posts. I glad to be here (actually I have already been in this forum under another name but that was a long time ago).

On this board use either \$\$ or [\tex][\/tex](without the \) to enclose the LaTeX.
\$\dfrac{x^2\sin(3x+1)}{\cos^3(x)}\$ gives $\dfrac{x^2\sin(3x+1)}{\cos^3(x)}$.

Learn a few basic things and then practice, practice, & more practice.
