Despite its bugs (with their workarounds), Grapher is an outstanding software that should please you. I !wish you as much fun as I’ve experienced using it.! !!!!!!!!!!!!Yves Barois! ! ! This manual (French and English versions), English documentation on Internet, various works built with Grapher, are available on :! ! ! <http://y.barois.free.fr/grapher/>" #3 Overview of Grapher! Summary.! ! ! ! ! ! ! ! ! ! ! ! ! ! ! Grapher is software specifically designed for Mac OS X to show various graphic representations of equations. It can graph the following mathematical expressions :! !• Explicit or implicit equations! !• Parametric curves and surfaces! !• Solutions of differential equations! !• Discrete sequences! !• Scalar and vector fields! !• Inequalities and Boolean equations! ! • Sets of points! Grapher presents a convivial interface which allows to quickly create professional-quality graphs. Moreover, it provides additio- nal tools such as :! !• Evaluation and integration! !• Animation! !• Regression curves! !• etc.! ! !Intuitive user interface.! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! #4 !Toolbar : ➊.! Use the toolbar to select the action of the cursor, to change the limits of the frame, to show the inspectors, etc..! ! To customize
