How To Set Window On Graphing Calculator
On the TI-84 Plus estimator, information technology'south difficult to get a dainty viewing window for your sequence on your beginning endeavour. Understanding the basics of sequence notation should help. Here are the variables used in the window of a sequence graph:
-
northMin: Where n starts counting. 1 is the default value.
-
northMax: Where n stops counting. Cull a value for nMax that is equally large every bit yous might demand.
-
PlotStart: First term number to be plotted; 1 is the default value.
-
PlotStep: Increase for the northward value, used only in graphing. 1 is the default value.
Remember, use the arrow keys to navigate the Window menu. Here are the steps to ready your graphing window:
-
Press [WINDOW] to admission the Window editor.
See the showtime screen.
In most cases, it is best to set up nMin, PlotStart, and PlotStep to one.
-
Enter nMax.
Cull a value of nMax that is equally big as y'all might need; try 100. Encounter the second screen.
-
Enter the Xmin.
Enter Xmin = 0 for an aesthetically pleasing graph.
-
Enter the Xmax.
How many terms do you desire to graph? Bold the PlotStep and northMin are 1, enter the number of terms you want to graph.
-
Enter the Ymin.
Enter a value a little smaller than the smallest y-value in the sequence. Sometimes you have to guess this value; in this sequence, the smallest y-value is ii, 0 was entered in the example.
-
Enter the Ymax.
Enter a value a petty larger than the largest y-value in the sequence. Sometimes you have to guess this value; in this sequence, the largest y-value was guessed to exist around 25, every bit shown in the second screen.
If the values of Xmax or Ymax are large, y'all might desire to adjust the Xscl or Yscl values accordingly.
Okay. You lot are fix to graph your sequence. If your sequence doesn't display every bit nicely every bit you had hoped, press [WINDOW] and arrange the variables accordingly.
Press [GRAPH]. See the graph. It looks like the Xmax needs to be larger so that all the terms in the sequence will graph.
