Create a graph and add equations
Use Grapher to create 2D and 3D graphs.
Create a new graph: Choose File > New, then choose the type of graph you want to create.
Add your own equation: Click the Add button 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 the Add button 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.
Edit an equation: Select an equation in the equations list, then update the equation in the edit field above the graph.
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.
