I never downvote because I hate it when I get downvoted without any explanation. (+) means "I like this wu, it's factual, well written and well researched. It's a good contribution to E2". (-) means "I dislike this wu but I'm too much a coward to /msg you. Moreover I believe it's a waste of time talking to you since you're too dumb to improve it anyways."

# Posting Math on E2

This document explains how to embedd scientific formulae in your posts on E2. The best way to add formulae in your posts is probably to write them with the TeX syntax (because it's very close to natural syntax) and then use the superdoc to generate the corresponding MathML tags. Here are typical scripts that you will find most useful.# Simple equations

Sample : 2x+3=0TeX script :

` 2x+3=0 `

MathML script :

<math><mrow> <mn>2</mn> <mi>x</mi> <mo>+</mo> <mn>3</mn> <mo>=</mo> <mn>0</mn> </mrow></math>Numbers are enclosed by a

`mn`

tag. Identifiers are enclosed by a `mi`

tag. Operators are enclosed by a `mo`

tag.
# Fractions and square roots

Sample : (a+1)/(b+1) + sqrt(c)TeX script :

` \frac{a+1}{b+1} + \sqrt{c+1} `

MathML script :

<math><mrow> <mfrac> <mrow><mi>a</mi><mo>+</mo><mn>1</mn></mrow> <mrow><mi>b</mi><mo>+</mo><mn>1</mn></mrow> </mfrac> <mo>+</mo> <msqrt> <mrow><mi>c</mi><mo>+</mo><mn>1</mn></mrow> </msqrt> </mrow></math>

# Parentheses and other delimiters

Sample : f(a/b)TeX script :

` f \left( \frac{a}{b} \right) `

MathML script :

<math><mrow> <mi>f</mi> <mfenced open="(" close=")"> <mfrac><mi>a</mi><mi>b</mi></mfrac> </mfenced> </mrow></math>It is possible to use different kinds of delimiters, for instace brackets and curly braces.

# Polynomials

Sample : ax^{3}+ bx

^{2}+ cx + d

TeX script :

`ax^3 + bx^2 + cx + d`

MathML script :

<math><mrow> <mi>a</mi> <msup> <mi>x</mi> <mn>3</mn> </msup> <mo>+</mo> <mi>b</mi> <msup> <mi>x</mi> <mn>2</mn> </msup> <mo>+</mo> <mi>c</mi> <mi>x</mi> <mo>+</mo> <mi>d</mi> </mrow></math>

# Sequences

Sample : u_{n+1}= 1 - u

_{n}

^{2}

TeX script :

` u_{n+1} = 1 - u_n^2 `

MathML script :

<math><mrow> <msub> <mi>u</mi> <mrow> <mi>n</mi> <mo>+</mo> <mn>1</mn> </mrow> </msub> <mo>=</mo> <mn>1</mn> <mo>-</mo> <msubsup> <mi>u</mi> <mi>n</mi> <mn>2</mn> </msubsup> </mrow></math>

# Series

Sample : Σ_{n=0}

^{+∞}a

_{n}x

^{n}

TeX script :

`\sum_{n=0}^{+\infty} a_n x^n`

MathML script :

<math><mrow> <munderover> <mo>∑><mo> <mrow><mi>n<mi><mo>=<mo><mn>0<mn><mrow> <mrow><mo>+<mo><mo>∞<mo><mrow> <munderover> <msub> <mi>a<mi> <mi>n<mi> <msub> <msup> <mi>x<mi> <mi>n<mi> <msup> <mrow></math>

# Integrals

Sample : ∫_{0}

^{∞}f(t) dt

TeX script :

`\int_{0}^{\infty} f(t) dt`

MathML script :

<math><mrow> <munderover> <mo>∫</mo> <mn>0</mn> <mo>∞</mo> </munderover> <mi>f(t)</mi> <mi>dt</mi> </mrow></math>

# Vectors

Sample : u^{→}

TeX script :

` \vec{u} `

MathML script :

<math><mrow> <mover> <mi>u</mi> <mo>→</mo> </mover> </mrow></math>
