Viewing the book comfortably

Adjusting the zoom level

You can enter a zoom level into the box located between the two magnifying glass icons to view the book in a specific zoom level.

You can also zoom in and out on the book using numerous ways:

Zoom in	Zoom out
Click on zoom in icon	Click on zoom out icon
Hold down Ctrl and scroll up using a mouse wheel	Hold down Ctrl and scroll down using a mouse wheel
Pinch in	Pinch out

There are two other useful icons to quickly adjust the zoom level:

Icon	Description
	Set the zoom level so that the page fills the width of your device.
	Set the zoom level so that the entire page is visible.

Changing the view mode

Clicking on the Change view mode button to the left of the zoom buttons will open up a list of book view modes that you can use to view your book. Depending on the view mode, the button can look different:

Icon	Name	Description
	Single page mode	Only one page is displayed at a time.
	Book mode	Two pages are displayed at a time with the same orientation as the book.
	Side-by-side mode	Two pages are displayed at a time, but not necessarily in the same orientation as the book.
	Scrolling mode	Similar to most document viewers - the pages are displayed vertically and you'd need to scroll up and down to go from page to page.

Calculator instructions

Software tools

Most of our books include an abundance of interactive content and software tools that will help you with your learning. We have included the most commonly used software packages on the navigation bar for the ease of access:

Icon	Name	Description
	Graphing package	The graphing package allows you to plot multiple functions onto the same graph. You can use the graphing package to find the axis intercepts of your functions, the domain and range of your functions, and much more!
	Statistics package	The statistics package allows you to analyse discrete, continuous, and categorical data. The software will not only calculate the 5-number summary of your data instantly, but it will also help you visualise your data using: histogram, box and whisker graph, stem plot, cumulative frequency graph.
	Scientific calculator	The scientific calculator allows you to do simple calculations like a real calculator. You can press the buttons or type your expression using your keyboard. For example: / means ÷, ^ raises a value to the exponent following, ! can be used for factorial notation. To evaluate your expression, you can press the = button or Enter on your keyboard.
	Measurement Tools	The measurement tools allow you to measure lengths or angles of shapes in the book as you would do with a real ruler and protractor. Clicking on the icon will show the ruler, clicking a second time will show the protractor, and clicking once more will remove the tools from the viewer. The measurement tools will scale as you zoom in or out on the page. To move the ruler and protractor, click anywhere within them and drag to position on the page. The ruler and protractor can both be rotated. For the ruler, move your mouse to the circle marked on the tool. For the protractor, move your mouse to the edge of the tool. For more accurate rotation, hold down the Ctrl key and the tools will snap to 15 degree intervals while being turned. If using a touch device, the tools will snap to 90 degree angles when rotated quickly. When using touch motion, rotation and positioning supports multiple touchpoints.

Creating notes

To create a sticky note:

1. Open a book in the Snowflake online reader.
2. Right-click on the book page (or the blue areas to the sides of the page) and select Add note.... A new note will appear, ready for text to be entered.
3. Enter the text you want to save.
4. To finish editing, click outside the note, or press the Esc key on the keyboard. If you are on an iPad, you can also close the on-screen keyboard, or tap outside of the note.

Saving notes

Your sticky notes are automatically saved online to the Snowflake cloud after they have been modified. Saving can take a few seconds - a spinning icon will be shown while your notes are being saved. A green tick will be displayed on the top-right of your note after the note has been saved successfully. Once saved successfully, the green tick icon will disappear after a couple of seconds.

Editing notes

To edit the text in a sticky note:

• Double-click the note, or
• Right-click the note, then click Edit note... in the pop-up menu

You can also:

• Drag and drop a note to a new place on the page
• Resize a note by dragging the right and bottom edges, or the bottom-right corner of the note
• Change the colour of a note by right-clicking on the note and selecting a colour from the menu
• Permanently delete a note by right-clicking on the note and clicking Delete note... in the pop-up menu

Writing mathematical expressions on the notes

Mathematical expressions can be entered in two main representations:

1. A simple form, surrounded by @ symbols. For example:
   • @x^2 - 16 = 0@ is displayed as: x^2 - 16 = 0
   • @4 sin(2 theta)@ is displayed as: 4 \sin\left(2 \theta\right)
2. The TeX typesetting language, surrounded by $ symbols (inline style) or $$ (display style), as supported by the KaTeX library. For example:
   • $x^2 - 16 = 0$ is displayed as: x^2 - 16 = 0
   • $$f(x) = \int_{-\infty}^\infty\hat f(\xi)\,e^{2 \pi i \xi x}\,d\xi$$ is displayed as: \displaystyle f(x) = \int_{-\infty}^\infty\hat f(\xi)\,e^{2 \pi i \xi x}\,d\xi

In both cases, mathematical expressions can be surrounded by normal text. For example:

This would display as:

In question 1a, x^2 - 16 = 0.

Therefore (x + 4) (x - 4) = 0, and so x = 4 or x = -4.

If an expression is not understood, it will be displayed unchanged when you are finished editing the note.

Simple form

Expressions in simple form can be constructed using numbers, letters (lower- and upper-case), and the following operators, functions, and constants (where x and y may be expressions themselves):

Notes list

A list of all of your sticky notes in the current document can be found by opening the table of contents, then selecting the Notes tab at the top.

Click on a note entry to jump to its page and position.

Hiding and showing sticky notes

Having too many sticky notes on a page can become distracting and sometimes the book's content can be covered by your notes. If this happens, you can hide all the notes on a page by right clicking on the book page, then clicking Toggle notes in the pop-up menu. Clicking Toggle notes again will reveal all the notes again. You can also press the n key on the keyboard for the same effect.

All notes will be reduced to a small circle. Hovering the mouse over the circle (or tapping the circle on a touch screen) will temporarily expand that note. However, hidden notes cannot be edited or moved.
