|| '''Visual Cue'''
|| '''Narration'''
|-
|| '''Slide 1'''

'''Title Slide'''
|| Welcome to the Spoken tutorial on '''Inserting line breaks in Equation.'''
|-
|| '''Slide 2'''

'''Learning Objectives'''
|| In this tutorial, we will learn to use,
* breqn package
* dmath for automatic line breaking
* \left and \right commands to adjust the delimiters.
* dmath* for line breaking without numbering
|-
|| '''Slide 3'''

'''System Requirements'''
|| To record this tutorial, I am using:
* Ubuntu Linux OS version 22.04
* TeXworks version 0.6.6
|-
|| '''Slide 4'''

'''Pre-requisites'''
|| To follow this tutorial, learners should have basic knowledge of LaTeX.
|-
|| '''Slide 5'''

'''Code files'''

The following code file is required to practice this tutorial:

1. breqn-eg.tex
|| The following code file is required to practice this tutorial.

This file is provided in the Code Files link of this tutorial page.
|-
||
|| Let us get started.
|-
|| '''Highlight:'''

'''\usepackage{breqn}'''
|| This command imports the '''breqn '''package.

It helps to automatically break long equations into multiple lines.
|-
|| '''Highlight:'''

'''Lines 13 to 23'''
|| Note the long equation.
|-
|| '''Highlight: '''

\begin{equation}

\end{equation}

Click the green Typeset button and show the output.

Place the cursor on the output.

|| We used '''\begin{equation}''' and '''\end{equation}''' to display the equation.

Click the green Typeset button to run the code.

Here is the output.

Observe that the equation is not properly aligned as per the margin.
|-
|| Comment line number 13 and 23.

Uncomment line number 14 and 22.

Click the green Typeset button to run the code.

Place the cursor on the output.

Highlight:

'''\begin{dmath} '''

'''\end{dmath}'''
|| Let us comment line number 13 and 23 and uncomment line number 14 and 22.

Let’s run the code.

Observe that the equation breaks into 3 lines.

The '''dmath''' environment from '''breqn''' breaks the equation into lines and numbers it.
|-
|| '''Highlight:'''

'''\left[ '''at line 16 starting and

'''\right] '''at line 20 ending
|| The '''\left''' and''' \right''' commands adjust de-limiter size to fit the enclosed content.

They automatically resize parentheses, brackets, and other delimiters.

Notice that the manual line break command \\ is not used.
|-
|| Comment lines 14 and 22

Uncomment lines 15 and 21

Click the green Typeset button
|| Let’s comment line number 14 and 22.

And uncomment line number 15 and 21.

Let’s run the code.

Here again the equation breaks into 3 lines.

The dmath* environment from breqn breaks the equation.

It does not display the equation number.
|-
|| '''Slide 6'''

'''Summary'''

In this tutorial, we have learnt to use:
* breqn package
* dmath for automatic line breaking
* \left and \right commands to adjust the delimiters.
* dmath* for line breaking without numbering
|| With this we come to the end of this tutorial.

Let us summarise.
|-
|| '''Slide 7'''

'''Assignment'''
|| As an '''Assignment'''

Test breqn's behavior with $...$ inline math
