Yes, thanks. +1. It's too early for an accept, there might come other answers.

comment Missing steps in the calculation of limit?
Thanks for the quick reply. But my problem is that in the application frequency is zero, I apply the limit for that case, as I mention in my question.

comment GCD of rationals
Thanks for the Wolfram Alpha reference too. Interesting site, though I guess you guys would use Mathematica. Also gives additional information like series representation and prime factorization. I took the liberty of adding a link to it.

@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??
