Description
Function Grapher is a full featured Graphing Utility that supports graphing two functions together.
It has the unique feature that you can save your work as a URL (website link).
Usage
To plot a function just type it into the function box.
Use 'x' as the variable like this:
Zooming and Re-centering
To zoom, use the zoom slider. To the left zooms in, to the right zooms out. When you let go of the slider it goes back to the middle so you can zoom more.
You can click-and-drag to move the graph around.
If you just click-and-release (without moving), then the spot you clicked on will be the new center
To reset the zoom to the original click on the Reset button.
Using 'a' Values
There is a slider with 'a =' on it. You can use 'a' in your formula and then use the slider to change the value of 'a' to see how it affects the graph.
Examples:
- x^a
- 2x-3a
- sin(a*x)
Note how I used a*x to multiply a and x. If I used ax (or xa) the program just gets confused.
