GeoGebra Applications is a book about the applications of GeoGebra software. GeoGebra is a dynamic and interactive mathematics software for geometry, algebra, calculus, trigonometry and statistics. This software provides a platform for exploring mathematical concepts collaboratively, whether in a physical classroom or a virtual learning environment. The application of this mathematical software is very essential from low levels of school to university level to foster mathematical experiments and discoveries. GeoGebra is a platform to connect enthusiastic teachers and students and offer them many opportunities to explore and learn about math. In our book we present many good examples how to use GeoGebra tools in solving different math problems, to explore with similar examples, to make interpretations and draw conclusions. All the book contains the procedures of how to construct a dynamic mathematical model and how to play with the corresponding applet. The book is a wealth of ready-made materials, where educators and students can find pre-designed applets, worksheets and lessons covering a wide range of topics and difficulty levels.
