Yardım:Matematiksel formüller

testwiki sitesinden
Gezinti kısmına atla Arama kısmına atla

MediaWiki yazılımı matematiksel ifadelerin biçimlendirilmesinde LaTeX ve AMSLaTeX yazılımlarını içeren TeX yazılımını kullanmaktadır. Bazı matematiksel formüller kişisel tercihlere bağlı olarak PNG, bazıları ise HTML olarak gözükebilir. Şablon:Türkçe değil


Kodlama

Matematiksel kodlar <math> ... </math> kodları arasına yazılır. Math markup goes inside <math> ... </math>. The edit toolbar has a button for this.


Tex kodları doğru yazılmadıkları zaman hata uyarısı verirler. Bu nedenle kodları doğru yazdığınızdan emin olmalısınız.


Sunum

It should be pointed out that most of these shortcomings have been addressed by Maynard Handley, but have not been released yet.

The alt attribute of the PNG images (the text that is displayed if your browser can't display images; Internet Explorer shows it up in the hover box) is the wikitext that produced them, excluding the <math> and </math>.

Apart from function and operator names, as is customary in mathematics for variables, letters are in italics; digits are not. For other text, (like variable labels) to avoid being rendered in italics like variables, use \mbox or \mathrm. For example, <math>\mbox{abc}</math> gives abc.

TeX ve HTML

Before introducing TeX markup for producing special characters, it should be noted that, as this comparison table shows, sometimes similar results can be achieved in HTML (see Help:Special characters).

TeX kodlaması TeX çıktısı HTML kodlaması HTML çıktısı
<math>\alpha\,</math> α &alpha; α
<math>\sqrt{2}</math> 2 &radic;2 √2
<math>\sqrt{1-e^2}</math> 1e2 &radic;<span style="text-decoration: overline;">1&minus;''e''&sup2;</div> 1−e²


as follows.

HTML'nin avantajları

  1. HTML ile yazılan formüller her zaman yazının bütünü gibi durur.
  2. HTML ile yazılan formüllerde, sayfanın arka planı, font türü, internet sunucusunun ayarları aktif olarak çalışır.
  3. HTML kullanarak yazılan formüller sayfa açılım hızını arttırır.


TeX kullanımının avantajları

  1. Tex kalite bakımından HTML'den ileri bir yazılımdır.
  2. Tex yazılımında "<math>x</math>" kodlaması matematiksel değişken anlamına gelir. Fakat HTML'de "x" kodlaması herhangi bir anlama gelebilir. Bu yüzden bilgiler daha kolay kaybolabilir.
  3. TeX yazılımı özellikle formül yazımı için tasarlanmıştır. Bu nedenle daha kolay ve daha işlevseldir.
  4. One consequence of point 1 is that TeX can be transformed into HTML, but not vice-versa. This means that on the server side we can always transform a formula, based on its complexity and location within the text, user preferences, type of browser, etc. Therefore, where possible, all the benefits of HTML can be retained, together with the benefits of TeX. It's true that the current situation is not ideal, but that's not a good reason to drop information/contents. It's more a reason to help improve the situation.
  5. Diğer önemli husus TeX MathML kodlamasına, bu kodlamayı destekleyen sunucular tarafından çevirlebilmektedir.
  6. TeX komutlarını kullanırken sunucu desteğine ya da diğer teknik desteklere ihtiyaç duymazsınız. Bu kodlamanın işlevselliğini serverler sağlamaktadır. Bu nedenle her türlü sunucuda, rahatlıkla yazıp kullanabileceğiniz bir kodlama türüdür.

Align with normal text flow

Due to the default css

img.tex { vertical-align: middle; }

an inline expression like NNexdx=2sinhN should look good.

If you need to align it otherwise, use <font style="vertical-align:-100%;"><math>...</math></font> and play with the vertical-align argument until you get it right; however, how it looks may depend on the browser and the browser settings.

Also note that if you rely on this workaround, if/when the rendering on the server gets fixed in future releases, as a result of this extra manual offset your formulae will suddenly be aligned incorrectly. So use it sparingly, if at all.

Forced PNG rendering

To force the formula to render as PNG, add \, (small space) at the end of the formula (where it is not rendered). This will force PNG if the user is in "HTML if simple" mode, but not for "HTML if possible" mode (math rendering settings in preferences).

You can also use \,\! (small space and negative space, which cancel out) anywhere inside the math tags. This does force PNG even in "HTML if possible" mode, unlike \,.

This could be useful to keep the rendering of formulae in a proof consistent, for example, or to fix formulae that render incorrectly in HTML (at one time, a^{2+2} rendered with an extra underscore), or to demonstrate how something is rendered when it would normally show up as HTML (as in the examples above).

For instance:

Syntax How it looks rendered
a^{c+2} ac+2
a^{c+2} \, ac+2
a^{\,\!c+2} ac+2
a^{b^{c+2}} abc+2 (WRONG with option "HTML if possible or else PNG"!)
a^{b^{c+2}} \, abc+2 (WRONG with option "HTML if possible or else PNG"!)
a^{b^{c+2}}\approx 5 abc+25 (due to "" correctly displayed, no code "\,\!" needed)
a^{b^{\,\!c+2}} abc+2
\int_{-N}^{N} e^x\, dx NNexdx


This has been tested with most of the formulae on this page, and seems to work perfectly.

You might want to include a comment in the HTML so people don't "correct" the formula by removing it:

<!-- The \,\! is to keep the formula rendered as PNG instead of HTML. Please don't remove it.-->

Color

Equations can use color:

  • {\color{Blue}x^2}+{\color{Brown}2x}-{\color{OliveGreen}1}
    x2+2x1
  • x_{1,2}=\frac{-b\pm\sqrt{\color{Red}b^2-4ac}}{2a}
    x1,2=b±b24ac2a

See here for all named colours supported by LaTeX.

Note that color should not be used as the only way to identify something because color blind people may not be able to distinguish between the two colors. See en:Wikipedia:Manual of Style#Formatting issues.
