لمحبي الرياضيات والحساب والهندسة والعلوم - واعتقد الفيزياء ايضا- تقدم مايكروسوفت هذا البرنامج المجاني وهو عبارة عن آلة حاسبة متقدمة جدا لحل المعادلات المختلفة ورسمها وتنفيذ العديد من العمليات الاخرى مثل امكانية التعرف الالي على كتابة المعادلات والرموز باليد 4.0.1108 51MB Microsoft Mathematics provides a set of mathematical tools that help students get school work done quickly and easily. With Microsoft Mathematics, students can learn to solve equations step-by-step while gaining a better understanding of fundamental concepts in pre-algebra, algebra, trigonometry, physics, chemistry, and calculus. Original show and plot functions have changed to show2d and plot2d In Microsoft Math 3.0, the show and plot functions were used to plot 2D graphs. In this version of the program, you must specify show2d and plot2d instead. If you open a worksheet file from a previous version of the product, any expressions that use show or plot will need to be updated. Unable to type or edit expression in worksheet input pane after pressing the left arrow key or the backspace key repeatedly You can use the backspace key or the left arrow key to move left so you can edit an expression in the worksheet input pane. However, if you press these keys repeatedly, the input pane may stop accepting input in some cases. To fix this, press the right arrow key once, and then you can type again. Changing the color scheme causes problems with high contrast displays If your computer display is set to High Contrast mode, some areas of the workspace may become unreadable when you change color schemes in Microsoft Mathematics. To fix this problem, turn High Contrast off and then turn it back on again. Screen reader does not read inline error messages In many cases, Microsoft Mathematics displays inline error messages to explain syntax errors or to describe a problem. To give screen readers access to this information, you can change your options to show these messages as popup dialogs instead. On the File tab, click Options, and then click Display inline error messages as popup messages. The appearance of 3D graphs is not optimal. Installation of Microsoft DirectX is recommended because it takes advantage of hardware acceleration options, such as video cards. By default, Microsoft Mathematics opens the DirectX Setup wizard when the Mathematics Setup Wizard is complete. However, if your computer does not have DirectX installed or cannot use the technology, Microsoft Mathematics uses an alternative rendering format for 3D graphs. '
