comment GCD of rationals
@WillieWong - Why did you remove the [GCD] tag? Because it's a new one? But it is about GCD, and the [GCD] tag may help people who're looking for information.

comment Explaining why sin and cos are *not* at right angles
The "boring statement" is interesting. I just posted about the Fourier series on electronics.stackexchange, and used this to explain an alternative definition (sum of only sines instead of sin + cos)! :-)

You're right, the sine and cosine in the quote seem to refer to functions. I'll fix it.

comment Explaining why sin and cos are *not* at right angles
@Rahul - I think I can see that. I see the curve of both functions, and they're indeed $\pi$/2 apart. That $\pi$/2 is in the argument of the function, in the function's value there's nothing of that left. I understand that the sine value 0.6 is Obama, but this guy claims that Obama and Bush are orthogonal. Two scalars!

@Hurkyl - The question is [here](electronics.stackexchange.com/questions/32269/). John is Telaclavo, I am stevenvh (I must have my existing account here merged with this new one). Most of the discussion has been deleted, however, in the name of peace :-)

comment Explaining why sin and cos are *not* at right angles
@Rahul - Yes, that's what John also used as argument: sin(x + $\pi$/2) = cos(x). But that only means that the sin and cos then are equal. Sin(37°) = 0.6 and cos(37°) = 0.8. How are 0.6 and 0.8 90° apart??

@Theo - It's odd then that nobody seems to have questioned the system, given that you need a calculator to solve just any problem :-)
