If you're confused about something, please comment so I can make it clearer!
So, many of you have been talking about your window settings and how they're a pain in the AAA's to guess-and-check over and over again until you get them to fit. (sorry, that was a really nerdy calculator joke, lol)
So here's a quick tip on how to use window and zoom options to not only cut down your guessing and checking, but maybe even give you more accurate maximums and minimums.
Today we'll be learning about the Zbox option, a tool that allows you to "crop" a graph, in almost the same manner as you would crop a photo in Photoshop.
I'll be using the same equation for this tutorial as I did for the last one: X(X+2)(X-2)(X-1)
1. Plug your equation into y=
2. Set your window to a size bigger than what you expect the graph to take up. (In this case 30)
3.Graph!
Now you may be thinking, "Woah, that window's way to big to see anything."
What you really want is all in here:
4. Press your zoom key, and select ZBOX.
5. You will get a graph with a crosshair cursor, move the crosshairs to the corner of the area you want to crop.
6. Hit enter. (Notice that the crosshairs have been replace with a square handle) Move your handle to the other corner of the area you want to crop. Notice that a box is being drawn around your crop area.
7. Hit enter again and Voila!
8. If you accidentally crop the wrong area or get stuck, use ZSTANDARD and Window to reset and type in your oversized Window variables again.
Hope this helps!
