TI-84 Plus C Graphing Calculator Important Keystrokes
The TI-84 Plus C graphing calculator offers some very advanced functions, but to get to those advanced features, you have to know the basic keys to press. The keys to press most often appear in the following list:
Math Functions and Constants on the TI-84 Plus C Graphing Calculator
Your TI-84 Plus C graphing calculator is quite capable of helping you out with math problems and actually comes equipped with ways to include constants and to input standard elements, such as π. The following list shows some of the more common and helpful math functions:
The Basics of Graphing on Your TI-84 Plus C Graphing Calculator
You bought the TI-84 Plus C graphing calculator to help you do graphs, and help you it does. The points in the following list walk you through the steps to take to get your TI-84 Plus C to display a graph:
TI-84 Plus C Graphing Calculator Zoom Commands
The TI-84 Plus C graphing calculator not only helps you make graphs, but its Zoom commands also help you highlight specific areas of a graph, redraw graphs in certain ratios, and otherwise tweak graphs to suit your needs. The following list shows you what each Zoom command does:
ZBox: Draws a box around a portion of the graph and redraws the graph in a viewing window that has the dimensions of the box.
Zoom In: Zooms in on the graph at the location of the cursor.
Zoom Out: Zooms out on the graph at the location of the cursor.
Ygopro for mac. ZDecimal: Draws the graph in a –6.6 ≤ x ≤ 6.6 and –4.1 ≤ y ≤ 4.1 window. When the graph is traced, the x-coordinate of the Trace cursor equals an integral multiple of 0.1.
ZSquare: Redraws the graph in a window that makes circles look like circles instead of ellipses.
ZStandard: Draws the graph in a –10 ≤ x ≤ 10, –10 ≤ y ≤ 10 window.
ZTrig: Draws the graph in a –11π/4 ≤ x ≤ 11π/4 and –4 ≤ y ≤ 4 window. When the graph is traced, the x-coordinate of the Trace cursor equals an integral multiple of π/24.
ZInteger: Redraws the graph so that when it is traced, the x-coordinate of the Trace cursor equals an integer.
ZoomStat: Finds an appropriate viewing window for stat plots.
ZoomFit: Finds an appropriate viewing window for graphing functions, parametric equations, polar equations, or sequences.
ZQuadrant1: This command graphs your function in a preset viewing window where 0 ≤ x ≤ 13.2 and 0 ≤ y ≤ 13.2. When you trace a function graphed in this window, the x-coordinate of the Trace cursor will be a multiple of 0.1.
ZFrac1/2: This command graphs your function in a preset viewing window where –66/2 ≤ x ≤ 66/2 and –41/2 ≤ y ≤ 41/2. When you trace a function graphed in thiswindow, the x-coordinate of the Trace cursor will be a multiple of 1/2.
ZFrac1/3, ZFrac 1/4, ZFrac1/5, ZFrac 1/8, ZFrac1/10: These commands graph your function in a preset viewing window and work in the same manner as ZFrac1/2 does. If you think of d as the denominator of your fraction, then the viewing window is –66/d ≤ x ≤ 66/d and –41/d ≤ y ≤ 41/d. Tracing with these commands let you trace the x-coordinates by multiples of 1/d.
TI-84 Plus C Graphing Calculator Special Menus
Not only does the TI-84 Plus C graphing calculator help you graph, but it also offers special menus you can use to look at distribution, probability, and even finances. The following list shows all the special menus you can access on the TI-84 Plus C:
I have an older-model Texas Instruments TI-84 Plus calculator that was running the operating system that Texas Instruments loaded on it a few years ago. I never realized that it mattered which version of the operating system my calculator was running until we started doing logarithms in College Algebra class I needed to do calculus homework and my calculator was missing the change of base formula (logBASE) that’s found under the MATH menu on the TI-84 Plus calculator.
I then decided that I needed to update the operating system on my calculator. The problem, however, is that I couldn’t find a simple guide on the Internet to show me how. I figured out how to do it on my own and now I bring you this guide. It takes about 5 minutes and requires a mini USB cable and a computer running Windows or Mac OS X.
Step 1: Download OS from Texas Instruments Website
The first step to updating your Texas Instruments calculator is to download the operating system file. Visit the TI-84 Plus download page and download the TI-84 Plus family Operating System. As of the publication of this article, the current version is 2.55. Save the file on the desktop of your computer.
Step 2: Download and Install TI Connect
To install the operating system to the calculator, you will need to download a program called TI Connect to your computer. Here are the download links: TI Connect for Windows or TI Connect for Mac.
Step 3: Connect Calculator, Send to TI Device
Plug the calculator into your computer using a mini USB cable. Don’t have a mini USB cable? Buy one here. Then open up the TI Connect application and select Send To TI Device.
Click the Select Device button that’s found at the top of the TI Connect window. The computer should scan and find your TI-84 Plus calculator if it is plugged in. Once it finds your calculator, click Select. Now the top-left corner of the TI Connect window should say “Sending to TI-84 Plus.”
Click the Browse button at the top of the TI Connect window. Find and select the operating system file that you downloaded in step 1. Now click Send to Device to load that operating system file to your calculator. The computer will warn you that updating the operating system will erase all information stored in RAM. This includes any formulas in the Y= menu, stat plots, or any other temporary information you may have saved on the device (essentially it will revert your calculator to factory settings as if you just bought it from the store). If this won’t be a problem, click OK.
Step 4: Receiving Operating System
You should now see a dialog box on your computer that shows the status of the operating system update. In addition, your calculator should say “Receiving Operating System” and show the status.
Step 5: Check to Verify Update
After the update is complete, check to make sure it worked. Click the 2nd button, then click MEM (located on the “+” key). Select About. It should now show the current operating system version. Compare this number with the version number that you downloaded in step 1. I downloaded version 2.55 and now my calculator says 2.55 on the About page. The update worked.
