Common Features

 * [[image:CalculatorPicker.PNG width="271" height="185" align="center"]] || ..... || The Calculator was developed for mathclips.ca. Click the icon at the top left to visit that resource.

There are actually three separate calculators. Click the picker at the top left to choose between them.

You can run the calculator in a new browser window.

One of the nicest features of the calculator is that you can download it as a SWF file for offline use. ||
 * [[image:iButton.PNG width="87" height="88" align="center"]] ||  || === Information ===

Each calculator has an **//i//** button for additional information including keyboard shortcuts and credits. ||
 * [[image:BasicBackgroundColourWidget.PNG width="175" height="10" align="center"]] ||  || === Background Colour ===

Click on a colour swatch at the bottom of the calculator to change the background colour. ||

**Basic Calculator**
 * [[image:BasicCalculator.PNG width="240" height="252" align="center" link="@http://mathclips.ca/calculator.html?mode=basic"]] || ...... || The Basic calculator operates like most simple calculators.

Press the **=** key to calculate the answer. This also places the answer in the system clipboard. You can switch to another application and **paste** the value.

@http://www.mathclips.ca/calculator.html?mode=basic is the direct link to the Basic Calculator. ||
 * [[image:BasicKeyboardShortcuts.PNG width="175" height="205" align="center"]] ||  || === Keyboard Shortcuts ===

You can use the buttons or the keyboard shortcuts to perform calculations.

If the Keyboard Shortcuts dialog is not displayed, go to the //i// button and select **Keyboard Shortcuts**. || top **Scientific Calculator**


 * [[image:ScientificCalculator.PNG width="185" height="294" align="center" link="@http://mathclips.ca/calculator.html?mode=sci"]] || ..... || The scientific calculator has additional mathematical operators.

Special keys include:


 * 2nd:** This performs the inverse operation and is used to calculate arcsin, cube roots, and powers.


 * ANS:** This returns the answer of the previous calculation.

The mathematical constants buttons along the left side allow the direct input of pi, e, and several lesser known values.

Press the **=** key to calculate the answer. This also places the answer in the system clipboard. You can switch to another application and **paste** the value.

@http://www.mathclips.ca/calculator.html?mode=scientific is the direct link to the Scientific Calculator. ||
 * [[image:ScientificCalculatorSettings.PNG width="154" height="232" align="center"]] ||  || === Settings ===

Access the Settings Dialog from the **//i//** button, **Mode** button or **Fix** button. The current settings are displayed at the top of the calculator window in a gorgeous lavender colour.

Switch between degree and radian mode.

Set a fixed number of decimal places.

Operate in base 2, 8, 10 or 16. For example, change the base to hex (16). Enter 5+5 and get the answer A. To see what that is in binary, use the settings to change the base to bin (2). It is 1010. Change the base back to dec (10) to see the answer you might have been expecting. ||
 * [[image:ScientificKeyboardShortcuts.PNG width="218" height="177" align="center"]] ||  || === Keyboard Shortcuts ===

The list of shortcuts is accessed from the **//i//** button. There is a much more extensive list than for the basic calculator due to all the additional operators. ||
 * [[image:ScientificCalculatorConversions.PNG width="179" height="214" align="center"]] ||  || === Conversions ===

To perform a conversion, first access the settings dialog (see above).

Next, click the conversion type. Kilograms to pounds has been selected in the image at left. The current conversion type is displayed at the top of the calculator window in orange.

Next, on the calculator, type a value and press the **Conv** key.

The display will show the units to avoid confusion. For example, 25 kg is about 55.1155655 lb. ||

**Graphing Calculator**


 * [[image:GraphingCalculator.PNG width="227" height="284" align="center"]] || ..... || The graphing calculator allows up to 3 functions to be plotted.

When the calculator opens, y1 and y2 are plotted. To plot y3, check the box to its left.

Click in the text box to change the equation. The text box will be yellow and the function not displayed if the equation is not a correct form. The most common mistake is to leave out the multiplication sign. For example, xsin(x) is not valid x*sin(x) is valid.

@http://www.mathclips.ca/calculator.html?mode=graphing is the direct link to the Graphing Calculator. || The graph can be solid or dashed, which is particularly useful if two functions are superimposed. ||
 * [[image:Graphing CalculatorDashedGraph.PNG width="269" align="center"]] ||  || Use the colour picker and the line style picker to the right of an equation to change its appearance.
 * [[image:GraphingCalculatorKeywords.PNG width="197" height="226" align="center"]] ||  || === Keywords ===

Access the Keywords Dialog from the **//i//** button. These are the functions that can be used in equations.

sin(x) 0.5ceil(2x) max(0.5, sin(x))
 * Sample functions:**

Notice that the parser can handle 2x, but not xceil(x). ||
 * [[image:GraphingCalculatorMouseModes.PNG width="173" height="457" align="center"]] ||  || === Mouse Modes ===

Various modes are available from the menu at the top left:


 * Normal:** This mode stops all interactions with the grid indicated below. Clicking on the grid allows you to reposition the calculato**r** (and any open dialogs) in the browser window.
 * Pan:** Click and drag on the graph to adjust its location in the window.
 * Locate:** Click to add a point and display its coordinates. Click again or drag to move the point.
 * Rectangle:** Draw a rectangle and the graph will change its window to match. Watch for a **Zoom Out** button to help you undo the change.
 * Zoom:** Choose a zoom factor. Click on the graph and it will zoom (2x will zoom in, 1/2 will zoom out).

The mouse mode is displayed in orange at the top of the calculator window. ||
 * [[image:GraphingCalculatorRadDeg.PNG width="280" height="17" align="center"]] ||  || === Angle Measure ===

Click rad or deg at the top of the window to change the mode back and forth. ||
 * ||  || Space ||
 * [[image:GraphingCalculatorCamera.PNG align="center"]] ||  || === Capturing Images ===

Use the Camera icon to take a screen shot of your work. Choose a region or "part of screen" to select your own region.

Once the image is ready, you can save it as a JPG or PNG depending on the setting at the bottom of the menu or view the image in your browser.

||
 * [[image:Graphing CalculatorWindowSettingsIcon.PNG align="center"]] ||  || === Window Settings ===

Directly enter values in order to change what part of the graph is displayed. Click the Window Settings icon to display the dialog or choose **Window** from the //**i**// button's menu. ||
 * [[image:mathclips/Graphing CalculatorWindowSettings.PNG width="290" height="301" align="center"]] ||  || Typing values in the fields has no affect on the graph unless you click **Apply Changes.**

To make a window in which the x and y scale use the same unit length, click the button to the right of the y-axis Maximum field. If you turn Auto scale off, you can force scale labels and ticks to be displayed in a custom fashion. ||
 * [[image:Graphing CalculatorEquationEntry.PNG width="341" height="469" align="center"]] ||  || === Number Entry and Equation Entry Dialogs ===

The Number Entry Dialog is particularly useful if you are using an interactive white board or are using Puffin Academy on a mobile device to display the calculator and do not have ready access to a keyboard. The Number Entry Dialog is like a virtual keyboard for the calculator.

To display the Number Entry Dialog, click the **123** icon.

The Equation Entry Dialog allows you to enter functions and parameters in an equation entry box. It works in conjunction with the Number Entry Dialog. To display the Equation Entry Dialog, make sure the Number Entry Dialog is displayed (use the **123** icon if it is not) and then click in one of the three equation entry boxes.

The parameter buttons (left hand column) are only active(white) if they are selected in the parameters list. The text on these buttons will update to reflect changes to the names of these parameters.(See below) ||
 * [[image:Graphing CalculatorTrigWindow.PNG width="555" height="274" align="center"]] ||  || === Graphing Trigonometric Functions ===

If you are using radian measure, you might find it handy to express the horizontal scale in terms of pi.

In the example at right, a scale of pi/3 is being used. ||
 * [[image:Graphing CalculatorLinearExample.PNG width="506" height="248" align="center"]] ||  || === Loading Examples ===

Go to the **File** menu and select **Load Example**.

If you click on Linear Functions and close the pod, you should see three lines as well as two active parameters, //b// and //m//. If the parameters pod is not displayed, click on the **Parameters** button.

Notice how the first equation must be written m*x since mx might be the name of another parameter. ||
 * [[image:Graphing CalculatorParameterSettings.PNG width="363" height="234" align="center"]] ||  || === Parameters ===

Drag the black triangle on the number line next to a parameter to change its value. You can also type to the right of the equals sign. Typing to the left of the equals sign changes the name of the parameter. Only parameters with a green check mark are active.

To change the values displayed on the number line, click the blue triangle to the right and edit the values in the Settings dialog that appears. All of the dialogs can be dragged by their title bar. If these settings are too low in the window, they can be dragged to a more convenient spot. ||
 * [[image:Graphing CalculatorSavingLoading.PNG width="193" height="123" align="center"]] ||  || === Saving and Loading ===

From the file menu, choose **Save Graphs**. Make sure that the file is saved as a .xml file.

Use **Load Graphs**, to locate and open a previously saved .xml file. ||
