Works beautifully, but strangest way to do this that I can imagine. The resulting equation will have black anchor points around it which you can drag to make the equation smoothly and continuously change its height, width, etc. Then hit Command-V to “paste”, and to my astonishment Grapher will suddenly “paste” a perfect copy of the equation in a NEW place on your graph (NOT in the rectangle you made, oddly enough). Type an equation in the usual way as if you were going to graph it, drag across it to highlight it, and use Command-C to copy it., Then use Object>Insert Rectangle to draw a rectangle on your graph, CLICK on that rectangle to select it. Oh my Gosh, I just found by absolute sheer luck a way to answer my own question about creating equation labels for your graphs. Stay tuned for the next installment: Grapher – Using Parameters. I hope this introductory tutorial on Grapher – Getting Started was useful. Ordinarily I prefer to save the whole worksheet, but Copy As can be useful for quickly grabbing a graph and pasting it somewhere (e.g., email or tutoring software) for a student to see.

A second option is to right-click on the graph and select the Copy As option this lets you copy just the graph part to Mac OS’ clipboard as either a TIFF, PDF, or EPS file (equations will not be included). You can save the entire worksheet for later use via the File -> Save menu Grapher will store it in a. For an overview of Grapher’s built-in function capabilities, go to the menu under Help -> Show Built-In Definitions. Grapher also includes more exotic functions such as the gamma function, erf, and Bessel functions. These include trigonometric functions such as sine and cosine, inverse trigonometric functions, hyperbolic functions, e, and ln. Grapher also has a number of built-in functions: Note that that the default range for theta is 0 to 2π. Note that “θ” can be entered by typing in the word “theta” Grapher will automatically convert it to the theta symbol. Just remember to use “r” and “θ” instead of “y” and “x”, and Grapher will immediately understand that this equation is in polar coordinates. In fact, you can plot them simultaneously with rectangular equations. While Grapher has polar graph paper, you can plot polar equations equally well on the default axes. If you get tired of looking at a particular equation, you can uncheck the check box to its left, and its graph will temporarily disappear. If you click on the ellipse equation, it gets selected and the other function is greyed out if you click on the first equation, it gets selected and the ellipse gets greyed out. Note that there are now two equations in the Equation List. If you type in that equation and hit enter, Grapher immediately draws a plot and enters the new equation into the equation list: Explicit EquationsĮxplicit equations have the form y = f(x), where the y is all by itself on the left hand side of the “=”, and there is some function of x on the right. This will be covered in subsequent blog posts.
More complicated expressions can be entered with the help of the Equation Palette. By the way, Grapher does not recognize square brackets when nesting parentheses – so restrain yourself and just use the rounded ones.
This is useful for keeping track of nested parentheses, but is sometimes confusing for those of us who are used to entering parentheses one at a time. If you type in a parenthesis, Grapher will automatically insert a pair of parentheses, with the expectation that you will start typing your expression in the middle. The same principle applies to denominators – when finished with the denominator, hit the right arrow key to let Grapher know that the rest of the equation is not part of the denominator. Otherwise any subsequent typing will be considered as part of the exponent. When you have finished typing in an exponent, you have to hit the right arrow key in order to signal to Grapher that the exponent is finished. There are, however, a few quirks to keep in mind. Multiplication uses the “*” key, although you can often leave it out, e.g., 5x instead of 5*x. Division is handled with the “/” key, exponentiation with the “^” key. Entering EquationsĮntering equations is very intuitive with Grapher – just type them into the equation editor much as you would write them on paper. Grapher’s worksheet has three panes: the equation editor on the top, where you will enter your equation the equation list on the left, which keeps track of the different equations that are being displayed and the graph area itself.
