Analytic Geometry

IntroductionnnThe programme "Analytic Geometry" for Android™ is a flexible system designed for representing geometrical objects (on an OpenGL basis) in a rotatable 3d coordinate system, using parallel or central projection.nnThe programme supports the following objects: Point, vector, line segment, straight line, circle, ellipse, rectangular solid, tetrahedron, pyramid, prism, sphere, cone, cylinder and torus.nnDistances and intersections can be calculated for the most often used combinations of objects.
The objects resulting from these calculations are added to the scene and are adapted automatically, when one of the initial objects changes.nnAlso the elementary level of calculations is included.
2 vectors can be tested for collinearity or 3 vectors for linear indepency.
In addition linear combinations of vectors can be drawn.nnAs a bonus, the graph of a function of two variables and that of a function in parametric form can be added to the scene.nnThere is the option to show an objects data in a portion of the screen.nnOf course, the whole scene can be saved and reloaded.nnThose of you interested in mathematics outside the educational sector, too, will enjoy the capabilities of the programme.nnThe emphasis is on a flexible representation of the scene as well as on the calculations of distances and intersections.nnWe have added a learning aid, that introduces the basic definitions and concepts of analytic geometry.nn™ Android is a trademark of Google Inc.
