 Jun11 revised Missing steps in the calculation of limit? added 13 characters in body Jun11 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. Jun11 asked Missing steps in the calculation of limit? May31 revised GCD of rationals added link to site May31 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. May31 suggested approved edit on GCD of rationals May30 awarded Nice Question May29 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.

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)! :-) May24 revised Explaining why sin and cos are *not* at right angles fixed lapsus in equation May24 revised Explaining why sin and cos are *not* at right angles added 32 characters in body May24 comment Explaining why sin and cos are *not* at right angles You're right, the sine and cosine in the quote seem to refer to functions. I'll fix it. May24 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! May24 comment Explaining why sin and cos are *not* at right angles @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 :-) May24 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??
