In the Fourier series, we use two functions, namely sin(x) and cos(x) to construct "almost" all functions f(x). The fact that we can do this with just two Functions are not intuitive, in this problem we will elaborate on why Fourier series can work. (a) Take any two functions g(x) and h(x), for example g(x) = 1 and h(x) = x. Is with these two functions you can always construct a specific f(x) function? (Take f(x) example that you think is easy)
We know that f(x) and f '(x) are continuous and f '' (x) is piecewise continous for all x, on the interval -L < x ≤ L f(x) = (x / L) (1 - |x / L|) We also now that the top equation in the picture is true. Using the relevant info show that the Fourier series in the picture is correct.
