Graph With A Ti83 Dimension Mismatch

When you graph an equation on a TI-83 calculator, it's important that you can see the entire graph and it fits on the screen. If you have the dimensions for the x-axis and y-axis set to the same scale, it's difficult to see graphs that don't have similar x and y values. To make it easier to view the graph, customize the dimensions of the axes and set them to different scales.


Instructions


1. Press the "Y=" key in the top left corner of the calculator and enter the equation you want to graph.


2. Press the "Window" key next to the "Y=" key to edit the dimensions of the graph. This menu allows you to specify the minimum and maximum values of the x-axis and y-axis. Press the down arrow to scroll down the the value you want to edit, then type a new value and press "Enter." Edit each value until you are satisfied with the dimensions.


3. Press the "Graph" key in the top right corner of the calculator. The graph is displayed on the screen with the axes dimensions set to the ones you entered. If the area of the graph you want to view doesn't appear on the screen, press the "Window" key and change the dimensions again.


4. Press the "2nd" key, then "Quit" to exit the graph and go to the home screen.
