Thread: test, this is only a test of the latex system

Hi,
I am just trying to learn how to use latex!
\sqrt{4}=2

\int {x}^{3 }dx
\int {x}^{3}dx
After looking at the preview this doesn't look correct. Can someone please help me out?

You need to wrap them in tex tags

Code:

\int_{a}^{b}f(x) \, dx

Code:

\sqrt{4}=2

Thanks!!

Why is the integral giving me an error? I wrote \int_{a}^{b}f(x) \, dx with {math} at the beginning and {/math} at the end? I DID use [] instead of {}

You are using [tex] [/ math]

tags with out the space instead of

[tex] [/ tex] tags

Due to technical difficulties you must use the 2nd set of tags.

[tex] \int_{a}^{b} f(x) \, dx [/ tex] again remove the space

Tip: if you want to display actual LaTeX code, use the noparse tags around the whole thing. Then you can avoid awkward circumlocutions such as "but without the space".

That is [noparse] [/noparse] tags.

(and I am still surprised that that works correctly! )

I'm bad at matrix latex
