【Grapher】

　　You use Grapher to visualize and analyze implicit and explicit equations. You can graph equations as two– or three–dimensional graphs, and export them as images or animations.

　　Grapher是MacOS内置的函数绘图软件（视觉化函数），可以绘制2维3维函数，并且可以导出成图片或动画。

【Create a graph and add equations】

　　Add your own equation:  Click Add  in the lower-left corner of the Grapher window, then choose New Equation to create your own equation.

　　Add an equation from a template:  Click Add  in the lower-left corner of the Grapher window, then choose New Equation From Template to add parametric equations, curves equations, vector field equations, or series from templates.

　　Add an element to an equation:  Click the Add Elements pop-up menu  to the right of the equation field, then choose Show Equation Palette. You use the Equation Palette to add standard elements (exponentiation, roots, and absolute values), operators, Greek letters, and symbols to your equations.
