Hopefully people actually read this and take heed, just so that I haven't wasted 30 mins of my valuable time.

PS. Point out anything that I've missed out/got wrong. Thanks, Nathan

LaTeX is a special type of coding which can help you and others when posting for help on the HSN Maths forums. Basically, it stops confusion when it comes to things like:

x2/5x+3

I mean, is this

, , or something entirely different?

It's really simple to use once you get the hang of it, and for the basics, you only need to remember a few simple words that'll get you writing equations in no time at all.

__Writing in LaTeX__To write in LaTeX in this forum, you need to put the LaTeX in [tex ] and [/tex ] tags. For example,

CODE

[tex]x^2[/tex]

becomes

**Plus/Minus**

To use the , use

CODE

[tex]\pm[/tex]

**Multiplying and Dividing**

For , you would use

CODE

[tex]2 \times 2= 4[/tex]

For , you would use

CODE

[tex]4 \div 2 = 2[/tex]

**Fractions**

Example: would be

CODE

[tex]\frac{x}{2}[/tex]

Note the backslash (\) and use of curly brackets ({&}). If you miss out the \ or use the wrong type of brackets, then the code won't work!

**Multiple lines of working**

You can put more than 1 line of working in [tex ] tags. All you need to do is put a double backslash (\\) at the start of each new line.

CODE

[tex]\\12y=24

\\y=2[/tex]

\\y=2[/tex]

**Calculus**

For , use

CODE

[tex]\frac{d}{dx}x^2=2x[/tex]

For , use

CODE

[tex]\int 2x dx = x^2[/tex]

**Greek Letters**

would be

CODE

[tex]\pi \theta \delta \alpha[/tex]

**Fractions**

To get larger fractions, either use "display" tags rather than "tex" ones, e.g. , or use "\dfrac", e.g.

**Alligning equations**

The "display" one is more powerful, since that lets you do multiple lines of equations aligned at the = sign, e.g.

CODE

[display]

y-b &=m(x-a) \\

y &= 2x + 3

[/display]

y-b &=m(x-a) \\

y &= 2x + 3

[/display]

The "&=" is used instead of just "=", since the & symbol tells latex where you want things to line up.

The only other thing I would point out is

**trig**- if you just do "sin x" it looks funny - . You should really do "\sin x", with the slash, so that the "sin" bit appears upright: .

This also applies to "\cos x" and "\tan x".

**Logs**

Also, for logs:

CODE

[tex]\log_{10}100=\log_{10}10^2=2[/tex]
