* Spaces do not do anything. Use plenty of them to make the commands easy to read | |||
** This here has 17 spaces in it (visible only in editor): <nowiki><math> a = b + c </math></nowiki> <math> a = b + c </math> | |||
* \text{} makes spaces visible and text into roman. | |||
** <nowiki><math> \text{This is like normal text} = This is math text </math></nowiki> <math> \text{This is like normal text} = This is math text </math> | |||
** \mathrm is similar but does not remove spaces. <nowiki><math> \mathrm{arc sinh} </math></nowiki> <math> \mathrm{arc sinh} </math> | |||
* \rm will make the whole thing to be in roman instead of italic. Spaces will still be removed. | |||
** <nowiki><math> Velocity = Speed </math></nowiki> <math> Velocity = Speed </math> | |||
** <nowiki><math> \rm Velocity = Speed </math></nowiki> <math> \rm Velocity = Speed </math> | |||
** {} can be used to limit its scope. <nowiki><math> { \rm Roman } = Italic</math></nowiki> <math> { \rm Roman } = Italic</math> | |||
* "\ " adds single space. | |||
** <nowiki><math> abb \ b </math></nowiki> <math> abb \ b </math> | |||
* \displaystyle makes tall equations bigger and more beautiful. Will apply on things like sums and fractions. | |||
** <nowiki><math> a= \frac{b}{c} + \sum_{k=1}^n a_k b_k </math></nowiki> <math> a= \frac{b}{c} + \sum_{k=1}^n a_k b_k </math> | |||
** <nowiki><math> \displaystyle a= \frac{b}{c} + \sum_{k=1}^n a_k b_k </math></nowiki> <math> \displaystyle a= \frac{b}{c} + \sum_{k=1}^n a_k b_k </math> | |||
* Long equations can be split to multiple separate <nowiki><math></nowiki> lines. It will look the same as if it was written in one go. | |||
** <nowiki><math> a+a+a+a+a+a+a+a+a+a+a++a+a+a+a+b+b+b+b+b+b++b+b+b+b+b++b+b+b+b+b </math></nowiki> <math> a+a+a+a+a+a+a+a+a+a+a++a+a+a+a+b+b+b+b+b+b++b+b+b+b+b++b+b+b+b+b </math> | |||

== Style == | |||
* Variables and letters that represent values should be in italic. | |||
* Text should be in roman. Text variables are not exactly proper thing to do but they are fine in our wiki. | |||
* Constant should be in roman. But this is often broke. | |||
* Multiletter variables are bad idea and should be avoided. If they are more like words (for example acronms) use roman, otherwise use italic. | |||
* Sub and superscripts that represent quantities should be italic. Otherwise they should be roman. For example <math> V_{\rm max}</math> (max is roman) but <math> V_{n+1}</math> (n is italic) | |||
* Mathematical operators are in roman. Usually this happens automatically. For example <math> \sin\alpha </math> (<nowiki><math> \sin\alpha </math></nowiki>). But some operators will require manually setting. For example <math> \frac{ \mathrm{d} x }{ \mathrm{d} t} </math> (<nowiki><math> \frac{ \mathrm{d} x }{ \mathrm{d} t} </math></nowiki>) and <math> \mathrm{arcsinh} </math> (<nowiki><math> \mathrm{arcsinh} </math></nowiki>). | |||
* Units are in roman and separated from numbers by a space. <math> h = \frac{ E }{ m \times 9.81 \ {\rm m/s^2} } </math> (<nowiki><math> h = \frac{ E }{ m \times 9.81 \ {\rm m/s^2} } </math></nowiki>) | |||
