Best ResponseYou've already chosen the best response.1same syntax ? no... the first one is \dfrac and 2nd is just \frac \(\dfrac{test}{this }\) `\(\dfrac{test}{this }\)` compared to \(\frac{test}{this }\) `\(\frac{test}{this }\)`

Best ResponseYou've already chosen the best response.1you can make the middle division bar longer by adding some spaces \(\huge\dfrac{~\dfrac{a}{b}~}{\dfrac{c}{d}}\)

Best ResponseYou've already chosen the best response.1I saw someone posted something and had a code at the middle of the text without taking another line, for example: sin\theta = \frac {1}{5}. but I don't know how to do. When I write, it always jumps into the next line. Show me, please @e.mccormick

Best ResponseYou've already chosen the best response.1and how to make it be bold

e.mccormick

Best ResponseYou've already chosen the best response.0This is where \tfrac{}{} and \dfrac{}{} can also help. \tfrac{}{}, Text Fraction, means to make it small, like inline text, no matter what. \dfrac{}{}, Display fraction, means make it large, like it was a stand alone equation, no matter what. This line is with \(\frac{1}{2}\) just \frac{}{} This line is with \(\tfrac{1}{2}\) just \tfrac{}{} This line is with \(\dfrac{1}{2}\) just \dfrac{}{} This block is with \[\frac{1}{2}\] just \frac{}{} This block is with \[\tfrac{1}{2}\] just \tfrac{}{} This block is with \[\dfrac{1}{2}\] just \dfrac{}{} Notice that the frac changes if it is inline or in a block, \(\backslash\)[ BLOCK \]. But the dfrac and tfrac do not.

Best ResponseYou've already chosen the best response.0The math fonts are for equations, but same ones are there for text. here is why: \textbf{Some text with spaces} \(\textbf{Some text with spaces}\) \mathbf{Some text with spaces} \(\mathbf{Some text with spaces}\) See the spaces and what happens to them in math mode?

Best ResponseYou've already chosen the best response.1I can see the difference. b stands for bold?

e.mccormick

Best ResponseYou've already chosen the best response.0Yes, the first and last are the same. Where the [dt]frac comes in really handy is when you need to make sure one is a large fraction inside another fraction. Or small, and so on. Large inline with text, so it is clear...

Best ResponseYou've already chosen the best response.0With the t/d fracs you can do \(\dfrac{d}{dx}\left( \dfrac{\dfrac{\tfrac{\pi}{4}+e^x}{x^e}}{14x^6+12x^37i}\right )\) inline and it is still readable.

Best ResponseYou've already chosen the best response.0@e.mccormick so how can I use it in everyday life e.g. when writing an email or a doc. ?

Best ResponseYou've already chosen the best response.0\(\LaTeX\) has many editors, which make it great for writing papers, books, and so on. Especially ones with formulas and graphs. In fact, I linked one in another post recently.

Best ResponseYou've already chosen the best response.0Near the bottom of this is a PDF with vectors, all done in \(\LaTeX\) http://openstudy.com/study#/updates/51ed5575e4b00daf471999bb And here is a bit on using the codes to do posts here. http://openstudy.com/study#/updates/51d89020e4b041c5c27459bb The same MathJax plugin can be added to blogs and other sites to do similar things elsewhere.

Best ResponseYou've already chosen the best response.0Yes. \(\LaTeX\) is free. For doing papers, I use MiKTeX on Windows as my TeX rendering engine and TeXmaker as my editor. However, to just try it for free you can use one of the online ones. https://www.writelatex.com/ http://www.codecogs.com/latex/eqneditor.php (Equations only, but makes them into grapics!) http://www.scribtex.com/ https://www.sharelatex.com/
