    No, no! You have to type `\begin{math}` and `\end{math}`. Not the dollar signs!

    Tip: 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.

    Hmm, in some cases, `\vec` is actually the vector with the box.

    Hm.. It is not very simple. There will be a lot of text and formuals and pictures.

    \[\hat{(\stackrel{\rightarrow}{a},\stackrel{\rightarrow}{b})}\]Try this one. `\hat{(\stackrel{\rightarrow}{a},\stackrel{\rightarrow}{b})}`

    Hm.. \vec does not work with \hat. What's a pity.

    `\stackrel{stuff on the top here}{stuff on the bottom here}` is used to write a thing above another. It's very hacky

    Oh, now I see it. \(\vec b\) is lower that \(\vec a\). If there was a method to combine \hat and \vec...

    (\vec{a}\widehat{\rule{0pt}{3.5mm},\,}\vec{b}) This works like this, but it does not work in OpenStudy.

    That is because OpenStudy has a very limited version of \(\TeX\) called MathJax.

    LaTeX is a very powerful instrument to write furmulas. But such things like this disappoint me.

    This is the angle between vector a and b.
