Asking for a friend: With the use of Fourier series, I'm trying to solve an ODE of the form L*y'' + R*y' + y/C = r(x), where r(x) = 1 - x^2 for |x| <= 1, i.e. has a period of 2. To do so I need to represent 1 - x^2 as a Fourier series. In doing so I have to integrate e^(-n * i * pi * x), but I've reached a stumbling block. [more inside]

Anyone know of an aftermaket car stereo head unit that will play nicely with the iPhone 3gs? I looked at the previous question related to this, but didn't see any specific model recs...various google searches and Crutchfield have led me to believe that the 3rd gen iPhones are having charging issues with some (or all?) models of aftermarket stereos. I'd love to hear if anyone has any first hand experience lately with buying a new stereo for use with a newer iPhone. I probably would spend up to $400 for something cool. Thanks in advance.
