A. Hello! A graphing calculator is very important in Calculus. A TI-89 is actually the best. It is so much better than TI-84. I suggest getting a Texas Instrument because it seems like it is the most reliable. Get a TI-89, it is worth it because the function allows you to do anything. My teacher said if you have a Ti-89, you don't need to know anything... HAHAHA i agree...

What type of graphing calculator should I buy for college?
Q. I am a dietetics major in college. I need a nice graphing calculator that will allow me to do calculus and stats. I need some recommendations please. I'm not sure what to buy and my math professor for the fall semester has been vague about what I need. I've seen ones with USB ports. Are those the type you can hook up to your laptop and pc, put in the calculations, and then print out your work? Please be tactful. Thanks.

A. I think a TI-83 Plus will be fine. You can get all the doodads to upload programs to it from your laptop but I think you will be fine using it to just graph and do calculations. Most classes will make you learn how to graph by hand anyways so you don't really need to have the print out capability...yet. Even so there are many free online graphing programs you can use for visuals - including stats. Hope this helps!

What kind of graphing calculator should I buy?
Q. What is the best model graphing calculator to buy and why? Also, what is the purpose of the cable that comes with it? I need one for a precalculus algebra class and later another more advanced calculus class.

A. For advanced calculus a TI 94 or other 90 series calculater is good, but for the precalculas and algebra the TI 84 or 84+ is good. the cable lets it connect to other calculaters to transfer data. also you can buy a cable to connect to the computer through usb 2.0 and transfer data to and from the calculater

Here's one of the first: It seems easy enough to use; it requires you have a Java Runtime Environment installed, however. Most newer computers should already have that though.

How do I turn off my graphing calculator?

A. If you look above the [AC/On] button, there should be a coloured "Off" text. So, by logical reasoning, you'd have to press [Shift][AC/On] to turn it off. If yours doesn't have any markings, refer to this picture to see what I'm talking about:

How do you solve for x and simplify equations on a graphing calculator ?
Q. I have a ti 84 plus graphing calculator and i am wondering if there is a way you can enter an equation then solve for x. I am also wondering if you can simplify expressions and equations with the graphing calculator.
Asked by ajugorji - Tue Sep 30 21:34:16 2008 - - 1 Answers - 0 Comments

A. It has a equation solver. Press the MATH button and scroll down to solver. You have to have the equation equal to zero before you to it in. So if the equation was 4x - 3 = 17. You would have to put in the equation as 4x -20 = 0.

Asked by xamoramoro - Tue Jan 27 23:10:59 2009 - - 2 Answers - 0 Comments

A. The most common graphing calculator is the TI-83 or the TI-83 Plus. I have one of those, and it's probably one of the cheapest ones around. Unfortunately, the TI-83 is quite slow for graphing; it takes a while to graph trig functions. I think the TI-83 Plus Silver Edition is a little quicker. The TI-85 is "super" cool because it can find derivatives with respect to x in the blink of an eye. However, I have heard some professors do not allow them on tests, so I don't really recommend you get one unless you want it for fun, as it is quite expensive. Hope this helped you :)

Asked by Paradigmishift - Mon Sep 28 16:46:19 2009 - - 1 Answers - 0 Comments

A. Yes, you'll need a mini-USB to regular USB cable in order to connect it to the computer. Normally it's included in the TI-84 Plus packaging when you buy it, but I doubt the school would give it to you. The cable, however, can be found in many electronics stores and is frequently used for other things, such as connecting together camcorders, digital cameras, cell phones, printers, etc. The software you need to transfer programs from your computer to your calculator is called TI-Connect. There are others, but TI-Connect is the "official" one made by Texas Instruments. It should come on a CD-ROM when you bought the calculator. If you lost it/don't have one, you can always download it here: Download and install TI-Connect. And make sure it' [cont.]
