 * Introduction to the Casio Classpad 330 CAS calculator **

toc The Classpad calculator is a very versatile tool for mathematics.

There are many __more__ functions on the calculator than we will use in the two years of VCE mathematics.

This is a brief introduction to the basics that you do need to know.



Icon Panel
The green strip at the bottom of the touch screen has a panel of icons.



The __**Settings**__ icon accesses the settings menu and is equivalent to tapping the icon at the top left corner of most screens.

The __**Menu**__ icon returns you to the main menu screen shown in the main calculator picture above.

The __**Main**__ icon takes you to the Main calculation screen and is equivalent to tapping the Main icon in the main menu screen.

__**Resize**__ and __**Swap**__ allow you to manipulate the screen when it has divided into two sections (eg when Graphing).

Main Screen


The main screen is accessed by tapping the Main icon on the green Icon Panel or by selecting the first option on the Menu.

The main screen is where you do all the typical arithmetic calculations that you would expect to use a calculator for.

Enter your arithmetic using the keypad (or the virtual keyboard: see below). Then press the blue EXE button to execute (find the answer).

The Main Screen is also where you can manipulate algebra, solve equations etc.

__**Menu Bar**__
Once you enter the Main screen, you will see a menu bar at the top of the screen.
 * [[image:00calc1settingsicon.GIF]]Controls the settings
 * **EDIT**menu includes:
 * **UNDO \ REDO** which works the same as in a wordprocessor
 * **COPY \ PASTE**which works the same as in a wordprocessor
 * instead of using COPY \ PASTE you can highlight and drag expressions or values into a new location
 * **ACTION** has a series of submenus full of useful maths commands and functions
 * **INTERACTIVE** has practically the same list of functions and commands as ACTION but they help you use the commands (a bit).

__**Button Bar**__
Under the menu bar is a strip of buttons.

The first icon on the left can be used to swap an answer between fraction (or an exact value) and a decimal.
 * Use your stylus to highlight the answer, then click on that icon.

__**Mode Bar**__
At the bottom of the screen is a line showing the various modes the calculator is currently in. You can change the mode by clicking on the relevant word. Click again to change back.
 * **ALG \ ASSIST** : Leave your calculator in **Algebra** mode for now.
 * **DECIMAL \ STANDARD :** In **Standard** mode**,**answers are given as exact values (including fractions).
 * In VCE maths we often ask for answers in exact values (surds, pi, etc are not evaluated)
 * **REAL \ CPLX :**Leave your calculator in REAL mode for now.
 * We will learn about complex numbers in Year 12 Specialist Maths.
 * **DEG \ RAD \ GRA :**Angles are given in Degrees or Radians or Gradians
 * Gradians are not studied in VCE maths.
 * The final icon on the right of the Mode bar is your battery indicator.

Virtual Keyboard
The Keyboard button on the keypad opens a virtual keyboard on the touch screen part of the calculator.

The virtual keyboard gives you access to a wide range of functions and symbols including all the standard functions found on a typical scientific calculator.

The virtual keyboard has four tabs along the top of the keyboard.

Each tab has several screens accessed using the big buttons along the bottom of the virtual keyboard.

You will use the MTH tab and the 2D tab the most.

When you enter one of the alternate screens within a tab the return symbol (shown here) appears in place of the screen button. Tap the return symbol to restore the original screen for that tab.

__**2D Tab**__
The 2D tab offers a lot of functions that are available in other parts of the calculator as well. The difference is that they look nicer when entered using the 2D options.

__Initial Screen of the 2D tab__

Enter a fraction

Enter a square root

Enter an nth root (eg cube root)

Raise to a power

Find the absolute value (or modulus)

Brackets (that resize to fit the contents)

Solve simultaneous equations (See solving simultaneous equations)

Enter a hybrid function (See hybrid functions)

__CALC Screen of the 2D tab__

Enter a matrix (See matrices)

Calculate a limit (See limits)

Calculate the sum of a series

Calculate a derivative (See differentiation)

Calculate an antiderivative or integral (See antidifferentiation)
