Latest revision as of 17:45, 18 November 2014

This page gives an overview of the new features in GeoGebra 4.0 since version 3.2. Please see our fully revised GeoGebra Help document for more detailed descriptions of each new tool and command.

You can install GeoGebra 4 by using our Webstart or Download option.

GeoGebra 4 will not run on Java 1.4.2, so you need to install at least Java 5 from java.com

Compatibility with GeoGebra 3.2

Details about compatibility with GeoGebra 3.2 can be found here: http://wiki.geogebra.org/en/Compatibility

GeoGebraPrim

Our version of GeoGebra for younger students is available here: http://www.geogebra.org/webstart/4.0/GeoGebraPrim.jnlp

* Restricted set of Tools available
* All available Tools visible at once
* Larger Font size
* Larger / Thicker Objects
* Just the Graphics View showing
* Easier to select objects
* Labeling of objects disabled (by default)
* Angles always between 0° and 180° (by default)
* Rounding to nearest whole number (by default)

Tools

New Tools

 Allows a Point to be created in the interior of a Polygon, Circle or Ellipse, or on the perimeter if you click there
 Hold down <Alt> to attach a Point to the interior of a shape (rather than the edge)
Draw a rectangle with the Move Tool first to draw onto a selected region of the Graphics View, or select an existing image first to draw into it. Right-hand mouse button acts as an eraser.

Changed Tools

As well as clicking on an object, then clicking on/to make a vector, you can now just drag an object to translate it (like a "Clone" Tool)

This has been completely rewritten so that dynamic texts are now very easy to make.

Just select the object you want to insert from the "Objects" drop-down menu and it will appear in a rectangle to indicate that it is a dynamic object, not plain text.

If you right-click on the rectangle, you can select "Definition" or "Value" for each dynamic object. There is also now a preview, a Symbol drop-down menu and a row of recently used symbols.

Also, Texts can now be moved by dragging while the Text Tool is selected.

Sliders can now be only moved by dragging while the Slider Tool is selected, or dragging with the right mouse button pressed when the Move Tool is selected.

Checkboxes can now be moved by dragging while the Checkbox Tool is selected.

You can now create a locus from a slider and a dependent point.

New Features

New Object Types

  • Multivariate functions, e.g. f(x, y) = x^2 + y^2
    You can also use them to define single variable functions, e.g. g(x) = f(x, 2) and functions of several variables eg f(a,b,c)=a+b+c
  • PolyLine
 Like a Polygon, but not closed and not filled. See the PolyLine Tool.
 eg 10 = x < 20
 You can use the commands MidPoint, Max, Min on these.

General Features

  • added function log(b, x) for base b
  • Worksheet export: Option to embed the ggb file into the HTML (encoded as Base64, uses the 'ggbBase64' parameter)

Scripting

All GeoGebra objects can now have a script associated with them. This can be a list of GeoGebra commands and/or some JavaScript. So for example an image or a circle can now act as a button.

The new Button and TextField objects have been specifically designed to support scripts. When you type some text into a textfield and press <Enter>, the text is passed to a script as %0, so you can have commands such as:
text = "%0"
Text[%0,(3,4)]

The text is also passed to JavaScript as a variable 'arg' allowing commands such as:
ggbApplet.evalCommand('input="' + arg + '"');

GeoGebra now has a built-in JavaScript interpreter. When exporting to a dynamic worksheet, the JavaScript for each button is exported to a separate function in the HTML file and the browser is used to run the JavaScript.

The Global JavaScript is available to all functions, and is also exported to the HTML file.

Extra supported commands:

* alert("hello");
* prompt("What's your favorite software","GeoGebra");

List Operations

<Object> ∈ <List> is an element of

<List> ⊆ <List> is subset of

<List> ⊂ <List> is subset of (strict)

<List> \ <List> set difference

 eg TableText[{{1,2},{3,4}},"c()"]
 eg TableText[{{1,2},{3,4}},"c|_"]
 eg TableText[{{1,2},{3,4}},"c||"]
 eg TableText[{{1,2},{3,4}},"c||||"]
 Simplify will now cancel factors from a fraction better, eg Simplify[(x-1)/(x^2-2x+1)]
 Factor has been much improved and gives better answers for simple factoring and also now
 copes with much harder problems eg Factor[ x^33 - 1 ]
Returns vertices of polygon
  • Integral[ <Function>, <Start x-Value>, <End x-Value>, <Boolean Evaluate> ]]
  • IntegralBetween[ <Function>, <Function>, <Start x-Value>, <End x-Value> ]]

 If a scaling factor is not specified the default is one. 
 When Use Density = false  no density scaling is performed 
 and histogram bar heights equal frequency values.

  • [[Command|GetTime[]
 Returns a list such as {647, 59, 39, 23, 28, 2, 2011, "February", "Monday", 2}
 ie the current date and time in this order:
 milliseconds, seconds, minutes, hours (0 - 23), date, month (1-12), year, month (as text), day (as text), day (1 = Sunday, 2 = Monday etc)

Calculates the maximum point for function in the given interval. Function should only have on maximum point in the interval.

  • Maximize[ <Number dependent>, <Number independent> ]

Calculates the independent number which gives the maximal value of the dependent number. The independent number must be a slider and the slider interval will be used as the search interval. If the construction is complicated, this command might fail or quit to avoid using too much processor time.

  • Minimize[ <Number dependent>, <Number independent> ]

Calculates the independent number which gives the minimal value of the dependent number. The independent number must be a slider and the slider interval will be used as the search interval. If the construction is complicated, this command might fail or quit to avoid using too much processor time.

  • LeftSum[ <Function>, <Start x-Value>, <End x-Value>, <Number of Rectangles> ]

Fits a function of the form a*b^x to the points in the list.
(Just like FitExp[], but to avoid the number e, as e is unknown to some pupils
 even if they know the exponential growth function.)
  • Fit[ <List of Points>,<List of Functions>]
Fits a linear combination of functions to the points in the list.
For example, with Points A, B, C, ...
  L={A, B, C, ...}, f(x)=1, g(x)=x, h(x)=e^x, F={f,g,h}
the command
  Fit{L,F}
gives a minimum squared errors curve fitting fit(x) = a + b x + c e^x
 Calculates the sum of squared errors, SSE, between the y-values
 of the points in the list and the function values of the
 x-values in the list.
 If we have some points in a list: L={A,B,C,D,E}
 and have done for example:
 f(x)=RegPoly[L,1] and g(x)=RegPoly[L,2]
 then we can decide the best fit, in the sense of the least sum of squared errors
 (Gauss), by comparing:
 sse_f=SumSquaredErrors[L,f] and sse_g=SumSquaredErrors[L,g].
