Author: Ambika Vanchinathan, Ketki Bhamble

Keywords: LaTeX, bm package, bold math symbols, multiline equations, mathbf, video tutorial.


Visual Cue Narration
Slide 1

Title slide

Welcome to the Spoken tutorial on Bold Fonts in Math Equations.
Slide 2

Learning Objectives

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.
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 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; 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 \bmcommand 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*) and bold the entire equation.
Slide 8

Thank you

Thank you for joining.
