Graph(equationA)

From JS-83 Wiki

There are two ways to graph a function.

Typing the Function Directly

To graph a function, type the following into the input box and hit enter:

graph('somefunction')

where somefunction is the part that FOLLOWS the equals sign (y=somefunction).

Notice that you must use single quotes around your function.

Example:

To graph y=2x+1, you would type:

graph('2*x+1')

To graph y=x^2+2x+1, you would type:

graph('pow(x,2)+2*x+1')

Using Data Storage

You can also graph using Data Storage. Store you equation into the Data Storage. Then to graph, you would type in the input box:

graph(Y?)

where ? would be the number of the function that you stored your equation to.

Example:

If I stored my equation y=2x+1 into Y1 under Data Storage, then to graph it, I would simply type:

graph(Y1)

If I stored my equation y=x^2+2x+1 into Y7, then to graph it, I would simply type:

graph(Y7)

Graphing Multiple Functions

By default, JS-83 draws a new graph everytime the 'graph' function is used. If you would like to have more than one graph at a time, here is what you must do:

• Expand the 'Graph' panel
• Click the 'Window' button
• Deselect 'Create New Graph'

You will still have to enter one graph at a time. But each new graph will be drawn on top of the previous graphs. To stop this behavior, simply reselect 'Create New Graph'.
