This is the fourth part of the GeoGebra 4.2 Sneak Peek Series. In the second and third part of this series, we have discussed about the Object Properties as well as Graphics and Layout sections. These sections are tabs located in the GeoGebra Preferences window. In this post, we discuss the remaining two more sections of the Preferences window, the Defaults and Advanced sections.
The Preferences window can be displayed by right clicking an object and then clicking Object Properties in the context menu. It can also be displayed using the the View menu and the choosing Advanced or using the Preferences icon located at the upper-right part of the Graphics view. Continue reading →
One of the most fundamental problems that gave birth to integral calculus was the calculation of areas bounded by curves. The Greeks used method of exhaustion to remedy this problem, particularly on finding the area of a circle. After Descartes’ and Fermat’s invention of Coordinate Geometry, algebraic solutions were utilized.
One of the strategies used to find the area under the function between and is to divide it into sub-intervals and form rectangles as shown in the first figure. Clearly, as the number of rectangles increases, the sum of all the areas of the rectangles gets closer and closer to the area of under the curve. Continue reading →
If you have used the GeoGebra Chrome App, you have surely noticed that there is no right click function. How do we solve this problem? GeoGebra expert Linda Fahlberg-Stojanovska gives us tips on how to remedy this problem in the tutorial below.
The Chrome App enables users to use GeoGebra on tablets and devices that do not support Java. Currently, GeoGebra developers are also developing real tablet apps particularly for the iPad and Android tablets.
In addition to the 5000 videos that I have shared to you last year, I have recently discovered more than 1500 links to mathematics video lectures in Pinterest. The links cover a wide variety of topics which include K-12 Mathematics, Math Interviews and Humor, Famous Mathematicians, Student Lectures, and many more.
The collection also includes undergraduate and graduate content topics such as Abstract Algebra, Graph Theory, Topology, Number Theory, Optimization, etc.
