GeoGebra 5.0.122.0 Description
GeoGebra 5.0.122.0 is an opensource utility built specifically for helping users design mathematical objects of several types used for calculus, algebra and geometry. Since this is a Javabased application, you should make sure you have previously installed the working environment on the computer.
 Userfriendly interface with clearcut options
It sports a clean interface that allows users to create mathematical objects by using dedicated tools or commands. The application offers quick access to different drawing tools that can be inserted in the working pane pretty easily.
GeoGebra 5.0.122.0 gives you the possibility to add points and vectors, and perform calculations with them (for example, you can measure the length of a vector), as well as include lines and axes, conic sections and arcs, curves, inequalities, intervals, and functions.
 Take advantage of a wide array of math functions
The app provides features for number creation and you can use the π and Euler constants for expressions and calculations, as well as work with angles, Boolean variables, matrix operations (addition, subtraction, multiplication), embedded text messages and images.
 Customize object properties
The inserted objects can be hidden or revealed in the graphical representation, filled with a color, as well as fixed to a certain position so you cannot move, redefine or delete them. Plus, it is possible to change the name of an object, label it with its value, create animations with numbers, angles or points, and enable the tracing mode for viewing an object’s position.
GeoGebra 5.0.122.0 offers support for two scripting languages (GGBScript and Javascript), so you can create a sequence of commands for designing or modifying the objects. What’s more, you may record the values for each object in a spreadsheet list, namely numbers, points, and vectors.
The generated projects can be saved to a file (e.g. HTML, PNG, EPS, GIF), uploaded on the developer’s website, or printed.
Features:
 Captions enabled for all objects
 New option Force Reflex Angle forces angles to be between 180 and 360 degrees
 Pressing toggles the focus between the Input Bar and the Graphics View
 Improvements to the way translation works
 Dynamic colors (Properties > Advanced tab). Set a function with range [0,1] for each color component (red, green, blue)
 Option for the grid to be bold
 Thumbnail saved in GGB files.
 Worksheets resized if they were saved on a larger screen
 Isometric grid
 Comparing objects of different types doesnt return an error, can now compare Text and Image objects
 If the Points Export_1 and Export_2 exist, they will be used to define the export rectangle (Export_1 and Export_2 must be within the visible area)
 Checkbox now consistent across all platforms
 Options > Checkbox Size > Regular/Large
 Perpendicular check added to Relation between two objects Tool
 Messages from Relation between two objects Tool rewritten
 Angular Bisector Command and Tool renamed to Angle Bisector
 Line Bisector Command and Tool renamed to Perpendicular Bisector
 BMP import
 Unicode fonts used in LaTeX equations
 LaTeX equations exported at full resolution
 in SVG and PDF export, option to export text as editable text or shapes. Stores the text either as text (lets you edit the text in eg InkScape) or as bezier curves (ie guaranteed to look the same even if the correct font is not installed).
 support for inline equations and linefeeds in LaTeX eg if x=9 find $ sqrt{ x } $
 Angle entered in rotate dialog box is remembered (if it is in degrees)
 Show All Objects in Graphics View menu
 Option for up to 15 decimal places
 x^0, x^1, x^7, x^8, x^9 now displayed nicely
 PGF/TikZ export
 added degree symbol to axes units
 new commandline parameter: antiAliasing=off
 defines e to be the Euler number when used in expressions (unless it has already been defined to something else)
 templates for 2x2 and 3x3 matrix in LaTeX dropdown menu
 Option to display numbers as Significant Figures (3,5,10,15)
 New options Edit > Select Descendents/Select Ancestors
 Doubleclick on an object in the Graphics View opens the redefine dialog, which now has a button to open the Properties dialog as well as OK and Apply buttons
 Input Field renamed to Input Bar
 Algebra window renamed to Algebra View
 Graphics window renamed to Graphics View
 Algorithm to decide which point to select added (rather than popping up a menu)
 Points in the form (a, b), (a + c, b + d) and (a + x(A), b + x(B)) are draggable (the variables a & b are updated accordingly)
 Ctrl + to zoom in, Ctrl  to zoom out
 New menu option Recompute all Objects (F9) which updates all the random numbers
 Set point style for lists of points
 Set line style for lists of lines
 Set filling style for lists of eg circles, polygons
 Set text style for lists of texts
 Animation of sliders
 f(x) is automatically named f(x) [ ie you can type just f(x) rather than f(x) = f(x) ]
 Shiftright drag will now allow a zoom that allows the aspect ratio to change
 you can now set the line thickness of polygons created with eg Sequence[Polygon[(i,i),(i+1,i),(i+1,i+1)],i,1,3]
 polygons can now have line thickness 0 (ie no edges)
 In Captions, %v is replaced by the value and %n by the name, eg The value of %n is %v
 Captions can now be surrounded by
... or
... to get bold or italic
 Altclick or F3: copy definition of selected object to the Input Bar
 F4: copy value of selected object to the Input Bar
 F5: copy name of selected object to the Input Bar
 Altscroll wheel: accelerated zoom
 Altdragging a selection rectangle puts a list of the objects selected in the Input Bar
 Hold down Alt when drawing a Line, Segment, Ray or Vector forces the angle to be a multiple of 15 degrees
 File > Open shows a preview image when available
 Properties > Color shows the color as an RGB triple in the preview pane eg (0,0,255)
 Area[Arc], Perimeter[Arc] work (treating the arc as a segment)
 sin(π x) now prints the π nicely
 Objects are now redefined from the input bar eg A = Point[f] then A = (1,2) will now make A a free object
 Shiftdoubleclick on a point on line/circle/function/etc in the Algebra View will allow you to set the coordinates without redefining it
 Record to Spreadsheet Tool: you can now altclick on a Point, Vector or Number to have its value(s) copied into columns A and B

replaced by newline in texts eg Text[GeoGebra
Rocks,(3,4)]
 cant have functions called sin, cos etc
 New point styles (plus, diamond, triangles)
 Size of the drawing pad in pixels can be obtained with pixelsWidth = x(Corner[5]) and pixelsHeight = y(Corner[5])
