Did you know that google calculator handles imaginary numbers?

I didn't even know google had a calculator but then again I don't use them other to search for nude raccoons.

Odd...

It'll handle: i+3*sinh(i*pi/2)
But not: i+3*sin(i*pi/2)

Hmm, that is weird. Well, it's definitely not perfect, I'm just impressed that it can handle complex numbers at all (not because it's hard, but because someone actually got paid to add this functionality)

Thank you for this magnificent revelation! I shall use this feature of Google for my calculations. My work is nearly complete now.

I'm a physics grad student and haven't owned a calculator in 5 years thanks to google :thumbsup:

I'll be impressed when you can write a program in C++, line by line, and it will compile it for you and let you download the finished product at the end.

That's not an equation.

Google's calc capabilities are indeed handy. I like to use for it for unit conversions (e.g. 1ft in m).

I will be impressed when we get google brain chips so that we can access the world information simply by thinking it.

I will be even more impressed when we get an open source add on that blocks the adds of said brain chips.

Hmm, so assuming your teachers allow you to use a calculator during tests, how do you manage not having one?

Yes, makes things so easy.

No, but Euler's equation is e^(i * pi) + 1 = 0. The point I was getting at was that Google would return 0.

That's incredibly easy to do with something like perl. We're talking < 10 lines of code.

After first year undergrad, you should never need one on a test. By that point, all questions will either be symbolic or require an order of magnitude calculation (ie adding exponents). Even if they allow one, you'll never have an opportunity to use it (unless you really can't do basic arithmetic, at which point it is a crutch and really only hinders you).

The only calculations ever required are on HW

Impressive...

i^i = 0.207879576 = e^(-pi/2) which is correct but not the only answer.

That's odd. When I was in school, we were still required to provide an answer. Most required a few decimals of precision. If you had time to do long division on paper, you were probably not gonna pass. Those were the classes where they gave you a sheet of equations and you had to derive the ones you actually needed to answer the problem. I hated college...
