|| In this tutorial, we will learn to,
* Write bold text in math mode
* Display '''trigonometric''' and '''Greek''' '''symbols''' in bold
* Avoid errors using nested braces 19.0
|-
|| '''Slide 3'''

'''System Requirements'''

* Learners should have basic knowledge of '''LaTeX'''
|-
|| '''Slide 5'''

'''Code files'''

The following code files are required to practice this tutorial:

1. bm-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{amsmath} '''

'''\usepackage{bm} '''

'''Highlight''':

'''{amsmath} '''

'''{bm} '''
|| These commands import the necessary packages:

The '''amsmath''' package for writing multiline equations.

The '''bm''' package for making bold symbols in math mode.
|-
|| Click the green Typeset button and show the output
|| Click the green '''Typeset''' button to run the code.

Here is the output.
|-
|| '''Highlight:'''

'''Line number 14'''
|| Here, '''\mathbf '''is used to convert the math equation into bold.

However, in the output, only the alphabets '''A''' and '''B''' appear in bold.

The trigonometric functions<nowiki>;</nowiki> '''sin''' and '''cos''' are not shown in bold.
|-
|| Comment the line number 16

Run the code and show the output
|| Let us comment line number 16 and run the code.

Observe that the complete equation is in bold.
|-
|| '''Highlight:'''

Line number 20
|| The '''\bm '''command makes everything bold, including trigonometric functions.

This command is available through the '''bm '''package included in the preamble.
|-
|| Let’s comment line number 22

Run the code and show the output
|| Let us comment line number 22 and run the code.

The output shows that the Greek letters '''φ''' (phi) and '''ω''' (omega) are not in bold.
|-
|| '''Highlight:'''

Line number 24
|| Here '''\mathbf''' has not converted the greek letters into bold.
|-
|| Let’s comment line number 26

Run the code and show the output
|| Let us comment line number 26 and run the code.

The output shows that the Greek letters '''φ''' and '''ω''' are now shown in bold.
|-
|| '''Highlight:'''

Line number 28.
|| Here '''\bm''' command has converted the greek letters into bold.
|-
|| Let’s comment line number 30

Run the code and show the output
|| Let us comment line number 30 and run the code.

The output shows equation with fraction, root, Greek, and trig functions in bold.
|-
|| '''Highlight:'''

Line number 32
|| Note that the''' \bm '''command has converted everything into bold.

Rarely, when the''' bm '''command throws an error, use one more set of braces.
|-
|| Let’s comment line number 34

Run the code and show the output
|| Let us see a displayed equation.

Let us comment line number 34 and run the code.

The output shows the complete displayed equation in bold.
|-
|| '''Highlight:'''

Lines 38 to 41
|| Note the '''bm '''command inside the equation environment
|-
|| Let’s comment line number 43

Run the code and show the output
|| Let us comment line number 43 and run the code.

The output displays a bold multiline equation.
|-
|| '''Highlight:'''

Lines 45 to 49
|| We have used the \bm command multiple times within the equations.

In the align environment, apply '''\bm''' before every '''(&)''' ampersand as well.
|-
|| '''Slide 6'''

'''Summary'''

'''In this we have learnt:'''
* Write bold text in math mode
* Display trigonometric and Greek symbols in bold.
* Avoid errors using nested braces
|| With this we come to the end of this tutorial.

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

'''Assignment'''

'''$\int_0^1 x^2 dx, \alpha + '''

'''\beta = \gamma$.'''
|| As an '''Assignment'''
* Bold this equation.
* Create a multiline equation (using align<nowiki>*</nowiki>) and bold the entire equation.
