Help me please.
How to write in LaTeX this expression? |dw:1362304526322:dw|
\[\displaystyle \hat{(\vec{a},\vec{b})}\]
``` \hat{(\vec{a},\vec{b})} ```
Is that what you wanted?
Lol. It does not work in Texmaker. Please look at the mistake.
No, no! You have to type `\begin{math}` and `\end{math}`. Not the dollar signs!
\[\hat{(\vec{a},\vec{b})}\]
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.
Then I don't know :-( @UnkleRhaukus will be able to help.
Anyway, thank you for your help. Type something in this topic http://openstudy.com/study#/updates/51331febe4b093a1d948e981 and i will give you a medal.
\[\hat{(\stackrel{\rightarrow}{a},\stackrel{\rightarrow}{b})}\]Try this one. `\hat{(\stackrel{\rightarrow}{a},\stackrel{\rightarrow}{b})}`
Yeah! Can you tell me what you have done?
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...
Well, this one was the only one I could figure out
(\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.
``` \[\widehat{(\vec a,\vec b)}\] ``` \[\widehat{(\vec a,\vec b)}\]
``` \[(\widehat{\vec a,\vec b})\] ``` \[(\widehat{\vec a,\vec b})\]
what does it mean?
This is the angle between vector a and b.
