Not my high school TI-82.

I'm taking Calc I this fall. I can borrow a graphing calculator for actual exams, but don't want to actually purchase one for day-to-day--or haul it around with me. I have an iPhone and a Nexus 7. Is there a graphing calculator app in one or the other app store that is clearly superior? I'm willing to pay, but under $10, ideally.
The Wolfram Alpha app does graphing.

Best answer: If you can borrow one for a day & dump the ROM (or find a ROM elsewhere), AlmostTI is pretty excellent as an emulator on the Nexus 7. (I've tried it with a TI-84 ROM, your mileage may vary for others.)
I'd also second Wolfram Alpha as a supplement, as it's useful for some things that calculators just can't match.

If you are sure your instructor will let you use calculators on quizzes and exams, spring for the actual calculator. IAAMath Professor, and I would not be likely to let you sub your phone for a calculator on assessments.
If this is just for hacking graphs while you're doing homework or something, WolframAlpha is great. (Just don't get used to relying on it to do all your differentiation for you!)

...and I have good reading comprehension. Now I see you've got a plan for your exams. Just make sure you've used it before walking into the exam, so you're not wasting time trying to figure out your calculator during the actual assessment.

Best answer: I have an app called Andie Graph, which mimics a TI-82. Its overkill for my needs, so I couldn't tell you how well it works, but it was free.

There's also Free42 for emulating the HP-42s (and printer) although I'd probably rather use a TI emulator.
Maybe one of the Unix emulators could be coerced to run on the Nexus? Or maybe one of the older DOS emus, in some kind of DOS VM for the Nexus? You can find links at ticalc.org

Best answer: I'd also note that you can buy a used TI-86 on Amazon for around $25. Which might ultimately be worth not dealing with two interfaces and the legwork to borrow for exams.

Response by poster: The actual TI-emulator seems like a great bet, here--a big thing is just not wanting to haul around yet another gadget every day--but I do think I'm also going to pick up the calculator since they're that cheap. Thanks!

Use the Wolfram Alpha website on whatever device you used to post this question at MetaFilter. It handles derivatives and integrals smoothly and visually.
Example with definite integral.
