THE GRAPHING BUTTONS

On a closer view at the top rows of buttons on the TI-83/TI-84 calculator. There should be five set differently from other buttons and they should possess the following labels;


[Y=]            [WINDOW]          [ZOOM]               [TRACE]              [GRAPH]

THE THREE BIG PROBLEMS


Sometimes When Graph Seem To Malfunction There Are Three Reasons Which Are;

Graph Function; if the graph is not properly entered it may be a problem.

Graph turned Off; the graphing function might be entered properly but it may not function as desired because it may be turned off.

Window View; if the window view is set on wrong size this could be a problem.

Detailed Here Are Solutions To The Three Big Problem.

 

Be Sure That The Graph Is Entered Properly;

Press the [Y=] key at the upper side of the calculator. This takes you to the Y= edit screen. You would see something as this.


Plot1 Plot2 Plot3


Y1=2X+1


Y2=


Y3=


Y4=


Y5=


Y6=

If you wish to try a simple expression be sure the calculator can do thus “Y1=X” this shouldn’t be hard as a plot of 45 degree should be created on the display graph screen.

Be Sure The Graph is Turned On;

The term “2X+1” is an illustration but you would see something like this Y= in the editor screen. If you see it then you add an expression like;

Plot1 Plot2 Plot3


Y1=


Y2=


Y3=


Y4=


Y5=


Y6=

If you wish to try a simple expression be sure the calculator can do thus “Y1=X” this shouldn’t be hard as a plot of 45 degree should be created on the display graph screen.

It is very possible that the graphing function might be turned off in the Y= edit screen and so an error might occur which kind look kind of tricky. The “=” sign you are trying to construct must be highlighted and if it’s not you must point to the “=” sign and press the [Enter] key to highlight it.

In Viewing The Window It Must Be Set To The Right Size And Location;

If the window view was set on a wrong size or location the calculator would plot nonetheless you won’t see it plot on screen. Many ways are available on adjusting the window view but an easier method is simply zooming out until you see what you are trying to draw on graph.

Press the [ZOOM] button at the top of the calculator and then click thrice to zoom out.


Do continuously until you see what you are trying to graph. Then press the [WINDOW] button at the top of the calculator to set the display characteristics.
