GeoGebra v4.4.8 - نرم افزار رسم شکل های هندسی

GeoGebra is a very useful mathematics tool for education in secondary schools, which brings together geometry, algebra and calculus. GeoGebra is also a dynamic geometry system, meaning you can do constructions with points, segments, vectors, lines, conic sections as well as functions and change them dynamically afterwards. On the other hand, equations and coordinates can be entered directly. Thus, GeoGebra has the ability to deal with variables for numbers, vectors and points, finds derivatives and integrals of functions and offers commands like Root or Extremum. These two views are characteristic of GeoGebra: an expression in the algebra window corresponds to an object in the geometry window and vice versa. Here are some key features of "GeoGebra": - 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
