1. how can I type or create the maths formula? 2. Can I ask the solutions for homework? such as maths, physics... thanks.
1. You will need a math keyboard like this... http://www.google.com/url?sa=t&sour...0ajoCQ&usg=AFQjCNGlm4QOfUjq_LzEUZKbikMk7tCcpg 2. You can ask questions but you may or may not get replies here. If it is homework you need answers for few here will help you. You need to learn on your own but if you get stuck I'm sure someone could help with a question or two.
You can also use LaTeX to display formulas. Here's an example: \(\frac{x}{2} \quad \textrm{or} \quad \frac{1}{2}x \) Just do a "quote" of this post to see it. There are editors available that will help you generate the code. I found this free editor : http://www.xm1math.net/texmaker/download.html#windows As for homework help...it is a general policy of this board not to do the work for you...however there are many VERY knowledgeable people on this board who are happy to help you out and point you in the right direction.
or if you're slick like me..... [noparse]\(\frac{x}{2} \quad \textrm{or} \quad \frac{1}{2}x \)[/noparse]
