Say you have the coefficients a_k of a Fourier series representation of some function x(t). You can easily then give x(t) as
$$x(t) = \sum_{k = -\infty}^{\infty} a_k e^{i k \omega_0 t}$$
But this doesn't do much good in telling you what the actual function looks like. For example, if we have...
So... I'm a sophomore in college right now, just completed my third semester. Up to this point I've been half a physics major and half a computer engineering major due to my indecision. My dilemma comes from the fact that while I love math and physics and could see myself working away in a...
