Table of Mathematical Symbols

[MathsFormula]

Hello could readers possibly type here some mathematical symbols that can be COPIED and PASTED when making our own posts. With symbols the maths is much easier to read. For example I found thread on this forum where someone explained how to make the SQUARE ROOT SYMBOL : √

Other useful symbols would be for PI, integration, alpha, beta. Also make a few FRACTIONS with numerator and denominator and we can then COPY the template and modify for our own use.

If readers familiar with these methods (codes) could post one or two symbols each then we'll soon manage to collate a large list. Thanks for your consideration.

I'll start off with the SQUARE ROOT symbol

√ √ √ √

I have told you before that there is no easy way of doing symbols on a web-board.
There is simply no way to cut&paste. You must learn LaTeX coding.

Below are several examples:

Let [TEX]\exp(i\theta)=\cos(\theta)+i\sin(\theta)[/TEX].
 
Then for a complex number [TEX]z=x+yi [/TEX] then [TEX]\exp(z)=e^x\left(\exp(iy)\right)[/TEX].
 
Now we define [TEX]\log(z)=\ln(|z|)+i\left(\text{arg}(z)+2k\pi\right),~k\in\mathbb{Z} [/TEX]
 
 [TEX] \begin{align*} \mathcal{P}(C)&=\mathcal{P}(C\cap A)+ \mathcal{P}(C\cap B)\\ &= \mathcal(P)(A)\mathcal{P}(C|A)+ \mathcal(P)(B)\mathcal{P}(C|B)\\&=(0.1)(0.01)+(0.9)(0.05)\end{align*}[/TEX]
 
 
[TEX] \begin{array}{l} y=\arctan\left(\frac{1}{2}\right)\\tan(y)=\frac{1}{2} \\sin(y)=\frac{1}{\sqrt{5}} \end{array} [/TEX]
 
[TEX]F(x)=\begin{cases}x^2\\ln(R)-1 &: 0\le x<\pi\\x^2 & \pi\le x<2\pi\end{cases}[/TEX]

Let \(\displaystyle \exp(i\theta)=\cos(\theta)+i\sin(\theta)\).

Then for a complex number \(\displaystyle z=x+yi \) then \(\displaystyle \exp(z)=e^x\left(\exp(iy)\right)\).

Now we define \(\displaystyle \log(z)=\ln(|z|)+i\left(\text{arg}(z)+2k\pi\right),~k\in\mathbb{Z} \)

\(\displaystyle \begin{align*} \mathcal{P}(C)&=\mathcal{P}(C\cap A)+ \mathcal{P}(C\cap B)\\ &= \mathcal(P)(A)\mathcal{P}(C|A)+ \mathcal(P)(B)\mathcal{P}(C|B)\\&=(0.1)(0.01)+(0.9)(0.05)\end{align*}\)


\(\displaystyle \begin{array}{l} y=\arctan\left(\frac{1}{2}\right)\\tan(y)=\frac{1}{2} \\sin(y)=\frac{1}{\sqrt{5}} \end{array} \)

\(\displaystyle F(x)=\begin{cases}x^2\\ln(R)-1 &: 0\le x<\pi\\x^2 & \pi\le x<2\pi\end{cases}\)

You can use <ALT> key on your keyboard to get some of the symbols (Less elegant than the LaTex display)

I use the <ALT> key to save time - sometimes!!

Thanks for those codes Soroban. Didn't know about them before. Will make maths equation typing a little more easy. For my basic maths requirement I won't need to go into the effort of learning LaTeX though thanks for the idea Subhotosh.Typed in a few &# random codes and is quite interesting:৴끄ᘊᴛ?Ȯ?

I agree with pka. Latex is very intuitive to learn, and you can make use of the Wikibook (http://en.m.wikibooks.org/wiki/LaTeX/Mathematics) or the online latex code generator (http://www.codecogs.com/latex/eqneditor.php) to help you. Ultimately, the comprehensive reference guide listing all symbols' coding is found at http://www.tex.ac.uk/ctan/info/symbols/comprehensive/symbols-a4.pdf .
