(4) Integrating cosmx with m = n−k and m = n+k proves orthogonality of the sines. Baron Jean Baptiste Joseph Fourier \(\left( 1768-1830 \right) \) introduced the idea that any periodic function can be represented by a series of sines and cosines which are harmonically related. Let f(x) be the function on [ 3;3] which is graphed below. A.
