symbols or signs: "infinity" symbol, "square root" sign, etc

[gmccormick]

Hello Everyone,

Can someone please tell me how to make the infinity sign and the square root sign. I know how to make the ^ that sign, but when I have x and the 2 is suppose to right up above it, or small 2 how do I make that on the computer. The infinity sign= (-6, inf) thats what I need.

Thank You
Ginger

Do you mean "how to make" them on these forums, or in some other context?

(If you're referring to the forums, then simply follow the instructions in the articles on LaTeX; the links are in the "Forum Help" pull-down menu at the very top of every forum page.)

Thank you!

Eliz.

Is this what you mean?

\(\displaystyle (-6,\infty)\)

If so, click on 'quote' at the upper right hand corner of my post to see the code I used to make it display that way.

Just testing LaTex, sorry.

That's OK. If you're a frequent poster, it is best to learn LaTex. Start out with something easy. There are many tutorials about to help you with the code. I type it in manually. Some use the MathType thing.

For instance, to wrap a box around something, use \boxed{}

For the sum(capital sigma) use \sum_{k=1}^{\infty}

Just a few examples.
