EditByBrothersoft: EdenGraph is a Graphing Calculator, built for Mac OS X, which is able to plot two-dimensional graphs using standard algebraic or trigonometric functions. Many mathematical packages only allow for Static, rendered images of graphs, whereas EdenGraph lets the user dynamically shift, track, or Magnify the current graph.
EdenGraph complements Mac OS X's methodology: the power of UNIX with an elegant, easy-to-use, and intuitive user interface. EdenGraph aims to provide Simplicity and usability, while harnessing the power and legacy of UNIX.
