Any good math/science/engineering apps out there?

I still have my HP-15C. Got me through engineering school, license exam, and my career so far. Not bad for a 27-year-old calculator. Still have its soft case.

Yeah, those things are becoming rare. I lived and slept with mine back when I was doing the numerous theory courses at the FAA Academy in OKC. Wish I still had it -- someone "borrowed" it many years ago.

Sure, you could download a calculator emulator or app the the previous posts are talking about.

But for quick unit conversions (ie meters to feet) AND advanced unit conversions (ie Joules to BTU's) use Wolfram Alpha's App.

Hell, use wolfram alpha.com. Sometimes it feels like cheating, but resources are resources.

The App simply links you up to the website, but I find it handy.

P.S. Wolfram Alpha can do some amazing things:

1) Differential Equations: y'' = 5y + 10y - Wolfram|Alpha'
2) Eigenvalues: http://www.wolframalpha.com/input/?i=eigenvalues++of+{{1,+1,+1},+{2,+2,+2},+{3,+3,+3 }}
3) Laplace Transformations: laplace transform of y'' = 2y' - 2y +2 - Wolfram|Alpha

Calculus Tools
com.andymc.derivative

That's been my project for the past several weeks.

Not nearly Wolfram, but it's standalone.

not bad but i really need stuff that has more post-calc classes

ie fourier, laplace, ODEs, PDEs..

I still use my Sharp EL-5100 which allows me to input and store many formulas and run calculations with any number of variables. Is there an app out there that does that for me? I can't seem to find any.

My Sharp is so old I am afraid its gonna die on me someday.

My favorite calculator ever! For a while I had a pc-based emulator for it. I can't find that now though--would need to boot up an old machine to find it I guess.

I posted some reviews of scientific for Android here. My favorites are Mathdroid, HandyCalc, and Arity.
