Math & Science ⇒ Entering Equations

[Sharon_syy]

Hi everyone,

I have just started using WinEdt with LaTeX which is compulsory for my project, so I am completely new to using the codes. I have several formulas and equations which needs to be entered in but I am only getting errors! Please help!

Here are the equations:

1. Volume of pyramid = 1/3 x Area of base x Perpendicular height
   = 1/3 x A x h
2. tan(π/5) = (s/2)/a
3. 1/2 x s/2 x s/(2tan(π/5)) = (s^2)/(8tan(π/5))
4. r = [a/(2tan(π/5)] [√((1-cosθ)/(1+cosθ))]

I want to align the equals signs so that one is below the other. The fractions to be in numerator and denominator form.
Here x is the multiplication sign. And square root to contain the fraction as we would usually write on paper.

Thank you! ^.^

I recommend to do some basic reading which will help you on with the first steps [1]. You will find some useful documents and other resources.

Hi Sharon,

welcome to the board!

Some reading is really necessary, as Thorsten said. Also I can recommend the documents, where he linked to.

In addition, specifically for writing math, have a look at amsmath and mathmode. Those documents guide to the best and effective math writing. Here, you could use the align environment of amsmath.

We gladly help. So what did you try, which code, and what errors did you get? I'm sure you don't meant "write all this for me from scratch", so just show us the code and we help to fix the problems.

Reading about the LaTeX basics is still necessary of course. If you don't understand something in a LaTeX introduction, just ask.
