hi peeps. just a quick one. (a) how would you go around working out the fourier for exponential functions.. simply something like e^x? (b) and how can this be applied to work out fourier series for cosh and sinh (considering cosh = e^x + e^-x / 2) etc etc.. first of all.. is e^x even or odd function.. i appreciate even function is: f(x) = f(-x) odd function is : -f(x) = f(-x) if for example , x =1.. e^x = e1... so f(x) = e1 so e1 = 2.718... e(-1) = 0.367... which is neither f(x) or -f(x)?? so theres a sticky point as its not clear whether this is even or odd..??
