<p>My son is taking a calc class and needs a TI 83 graphing calculator. Does anyone know of an online TI 83 graphing calculator that he can use?</p>
<p>He does not need an actual calculator as all the work is done at home so a (free) online calculator would be ideal for him.</p>
<p>We’ve done a google search, but came up empty so I thought I’d ask here.
Thanks in advance!!</p>
<p>Here is a thought on the calculator. If your son plans to take more advanced math classes or science classes that require advanced math (like physics), maybe you should buy him the calculator. These calculators (TI-83, TI-84) take some practice to use effectively, and there is something to be said for getting that practice during a class like calc (or pre-calc, or whatever). He doesn’t want to be struggling with how to use the tool later in school when he gets into a test situation or is crunching through a long problem set, and spends a lot of time trying to figure out the calculator. </p>
<p>I say this as an adult who recently decided to brush up my math skills in preparation for taking some college level physics classes. I researched calculators, and bought a TI-89. It is definitely more muscle than I need right now (and sometimes a bit irritating because it is so complex that I end up spending more time reading the manual than solving problems with it!). But I also know that getting familiar with it now will pay off a lot down the road. Certainly a TI-83 will do for what he is working on now, or maybe get a TI-84. But I would consider getting it for him so he is learning to use it as he does homework, not later on when time might be more critical.</p>
<p>There was an app called Pi-83 calculator but I just checked and it has been tossed from the App Store. It may still be available for Android. The best I can suggest is to check out the graphing and scientific calculator apps for a phone or tablet. They’re cheap and may fill the bill.</p>
<p>Thanks Lergnom but we don’t have a smart phone or a tablet for him to use. </p>
<p>Inparent - I agree that getting it now would be a better solution for many reasons, but a free or really cheap option fits our current budget better.</p>
<p>I have never looked for a calculator, but you might check Craigslist or Freecycle for one if you live in a relatively populated area.</p>
<p>Tried that already but thanks for the suggestion.</p>
<p>
</p>
<p>Really? What happens when he has to sit for a test???</p>
<p>He is learning calc at home so at this time, all testing occurs at home.</p>
<p>Does he need an actual TI-83 calculator? Because if you google “online graphing calculator” you will see a number of options that could do the equivalent of the TI-83.</p>
<p>When we googled it, we only found two and neither were really what the link claimed they were. So, I thought that I might find some help here.</p>
<p>If you’re using Windows 7 there is a more powerful calculator offered for free by Microsoft available for download here: [Download:</a> Microsoft Mathematics 4.0 - Microsoft Download Center - Download Details](<a href=“http://www.microsoft.com/downloads/en/details.aspx?FamilyID=9caca722-5235-401c-8d3f-9e242b794c3a]Download:”>http://www.microsoft.com/downloads/en/details.aspx?FamilyID=9caca722-5235-401c-8d3f-9e242b794c3a)</p>
<p>I haven’t played with it much, but it should have a decent number of the features you’re interested in.</p>
<p>You can also probably do anything that needs to be done for a calc class in [Wolfram</a> Alpha](<a href=“http://www.wolframalpha.com/]Wolfram”>http://www.wolframalpha.com/).</p>
<p>Finally, if you’re still on Windows XP, there’s the [Windows</a> Power Calculator](<a href=“Bing”>http://go.microsoft.com/fwlink/?LinkId=211474) which is considerably superior to the original calculator, and I still don’t know why they didn’t make it the default one in Windows 7 (or even add support for it).</p>
<p>Try googling “ti-83 emulator”.</p>
<p>There seem to be a bunch of them, however the ones I looked at all require a ROM dump from the calculator, which you generally can’t get unless you have the calculator and a link cable.</p>
<p>This one, wabbitemu, seems to be popular:</p>
<p>[Wabbitemu</a> Portable (TI-83+… emulator) 1.6.2 DT 1 | PortableApps.com - Portable software for USB, portable and cloud drives](<a href=“http://portableapps.com/node/31430]Wabbitemu”>Wabbitemu Portable (TI-83+... emulator) 1.6.2 DT 1 | PortableApps.com)</p>
<p>If also contains a link to download a ROM from TI, so maybe this gets around the problem of needing the calculator to get the ROM from.</p>
<p>I didn’t try any of these. Good luck!</p>
<p>Heck, Excel does pretty much everything that a calculator can do and more, and may be offered at a severely reduced price from the school, but it isn’t something you can use in an exam! Something that performs a calculator’s functions (even an advanced one) on a computer is pretty easy to find, and (as another poster noted) Wolfram will do a lot for free!</p>
<p>[url=<a href=“http://webgraphing.com%5Dwebgraphing.com%5B/url”>http://webgraphing.com]webgraphing.com[/url</a>] might be useful.</p>
<p>Open Office is an excellent free alternative to Excel, but something like the above is probably better suited.</p>
<p>Personally, I don’t understand the emphasis on graphing calculators in high school math (including AP calculus) except to support a single company’s overpriced products. The TI non-graphing calculators, such as the TI-36X Pro, are powerful and inexpensive, on the other hand.</p>
<p>Well, after doing a lot of googling today I have learned a few things. One, we have a TI86 calculator and that one may work. The calc text book he is using specificlly asks for the TI83 and then shows step by step which calculator buttons to use to solve a specific problem. the buttons on these two calculators are not identical, so we’ll need some help in figuring this all out. </p>
<p>Neither my DH or I are well equipped in this area. So, tomorrow I’ll be doing my best to figure this out.</p>
<p>And thank you to everyone who contributed!!!</p>
<p>He could also check with his friends, one of them may have a TI-83 they are not using this semester that he could borrow.</p>
