Best ResponseYou've already chosen the best response.0Lol. It does not work in Texmaker. Please look at the mistake.

Best ResponseYou've already chosen the best response.2No, no! You have to type `\begin{math}` and `\end{math}`. Not the dollar signs!

Best ResponseYou've already chosen the best response.2Tip: Avoid using all those TeXMakers and all when you have to make very simple documents with just text and math. Use http://www.artofproblemsolving.com/Resources/texer.php? and you can simply use $..$ and `$$...$$` or text.

Best ResponseYou've already chosen the best response.2Hmm, in some cases, `\vec` is actually the vector with the box.

Best ResponseYou've already chosen the best response.0Hm.. It is not very simple. There will be a lot of text and formuals and pictures.

Best ResponseYou've already chosen the best response.2\[\hat{(\stackrel{\rightarrow}{a},\stackrel{\rightarrow}{b})}\]Try this one. `\hat{(\stackrel{\rightarrow}{a},\stackrel{\rightarrow}{b})}`

Best ResponseYou've already chosen the best response.0Yeah! Can you tell me what you have done?

Best ResponseYou've already chosen the best response.0Hm.. \vec does not work with \hat. What's a pity.

Best ResponseYou've already chosen the best response.2`\stackrel{stuff on the top here}{stuff on the bottom here}` is used to write a thing above another. It's very hacky

Best ResponseYou've already chosen the best response.0Oh, now I see it. \(\vec b\) is lower that \(\vec a\). If there was a method to combine \hat and \vec...

Best ResponseYou've already chosen the best response.0(\vec{a}\widehat{\rule{0pt}{3.5mm},\,}\vec{b}) This works like this, but it does not work in OpenStudy.

Best ResponseYou've already chosen the best response.2That is because OpenStudy has a very limited version of \(\TeX\) called MathJax.

Best ResponseYou've already chosen the best response.0LaTeX is a very powerful instrument to write furmulas. But such things like this disappoint me.
