Function Grapher 2 is a software utility that helps you draw graphs of complicated mathematical functions

Function Grapher 2 is a software utility that helps you draw graphs of complicated mathematical functions. It has numerous features ranging from simple ones such as scaling and quality adjustment to advanced ones such as plotting the graph of dy/dx, integrating between two limits and plotting graphs of implicit functions.

Plotting graphs

Plotting a graph is simple. Type your function into the box provided and click Plot. For example, to plot the parabola y=x²+5x+6, type x^2 + 5*x + 6 in the box. For non-implicit functions (the default option), you must enter the expression as a function of x, and the graph of y=f(x) will be plotted.

Function Grapher 2 has many built-in mathematical functions that you can use. For example, to plot the sine wave, type sin x (or) sin(x) into the box. For a complete list of functions, see the Function List help topic.

To plot implicit functions, check the Implicit Function box and enter a function of x and y into the box. For example, to draw the circle x²+y²=25, enter x^2 + y^2 - 25 into the box. Do not include = signs in the function. The expression must be a function f(x,y) and the graph plotted is that of f(x,y)=0.

Function Grapher 2 can do more than just drawing graphs. You can scale the graph along the x-axis or y-axis by using the X Scale and Y Scale options. The Quality option adjusts the quality of the graph. A lower value results in faster drawing, but the graph looks more like a set of points. A higher value results in slower drawing but a complete, better graph. You can also plot the graph of dy/dx using the Plot dy/dx button. This plots the graph of y=f'(x).

Also, you can evaluate a definite integral of the function between two given limits using the Integrate button. You can evaluate the value of the function or of its derivative for any value of x using the Evaluate and Eval dy/dx buttons. The information box, which is filled after the graph has been drawn, contains statistics about the function, such as its maximum, minimum and mean values.

If you move the mouse over the graph, you can see the co-ordinates of the points on the graph. A * indicates that the point lies on the graph of the function.
