In this tutorial we will go over following features:

- Latex amsmath package
- Latex equation environment
- Using Simple equations like x = y + z
- Using Summation in equations
- Using Integration in equations
- Using Cases in equation (if condition based values of a variable)
- Using fractions to write multiple-row equations

Watch the following video to learn how to do these things:

The code used in this Video can be found below:

\documentclass{article}

\usepackage{amsmath}

\usepackage{amssymb}

\begin{document}

\title{Writing Equations with Latex by http://QuickLatex.blogspot.com}

\maketitle

\begin{equation}

%x = y + z

%f(x) = x ^ 2

%f(x) = x_1 + x_2 + x_3 + ......+ x_n

%f(x) = \sum_{i=1}^{n} {x_i}

%f(x) = \int_{i=1}^{n}{x_i}

%X=

%\begin{cases}

%5, \text{if X is divisible by 5}

%\\

%10, \text {if X is divisible by 10}

%\\

%-1, \text {otherwise}

%\end{cases}

X =

\frac{\substack{\sum_{i=1}^{n} {x_i}}}

{\substack{\sum_{i=20}^{50} {x_i}}}

\end{equation}

\end{document}

why exactly do you use \usepackage{amssymb}? is it useful to load it always with \usepackage{amsmath}?

ReplyDeleteand do you know, how to create chemical structures? that would be really great!

Dear Julia,

DeletePackage amsmath is used for additional mathematical symbols which are not there by default.

I will try to do some chemical symbols soon.

How do we use the latex templates and styles? For instance, I have downloaded siamltex.cls and copied it to C:\Program Files\MiKTeX 2.9\tex\latex\ltxmisc and ran texhash. Still I get the error "! LaTeX Error: File `siamltex.cls' not found." Any pointers?
