How to Graph on a Sentry Calculator

Graphing a function in mathematics can help you visualize the answer to a problem. The Sentry graphic scientific calculator is a basic calculator that has an additional graphing component. The Sentry graphic scientific calculator's user interface is designed to make graphing simple, so there's no getting lost in sub menus or trying to find the right key combinations. Whether you want to graph a parabolic function or a linear one, you can make a graph on a Sentry calculator in less than a minute.

Instructions

1. Set the range to a reasonable range for your function. For example, to graph "X^2" and have it show on your screen, the range should be set to -5<x>5 and -10<y>10. To set the range, press "Range" and type the values for Xmin, Xmax, Ymin and Ymax into the calculator. Press the "Exe" key after each entry.

2. Press "Graph."

3. Type your function into the calculator using the numeric keypad.

4. Press the "EXE" key to graph your function.

Tips & Warnings

• If your graph doesn't show on the screen, double check your range parameters to make sure they are reasonable for your function.
