Websince cos (mx) and cos (nx) are orthogonal functions. Consider an even function like cos (x)^3, only cosine (even) terms will appear. However without doing the integration, we can write cos (x) with complex numbers : cos (x) = (exp (ix)+exp (-ix))/2 then cos (x)^3 = 1/8* (exp (i3x)+3exp (ix)+3exp (-ix)+exp (-i3x)) = cos (3x)/4 + 3/4*cos (x) WebThe Fourier series is a sum of sine and cosine functions that describes a periodic signal. It is represented in either the trigonometric form or the exponential form. The toolbox provides this trigonometric Fourier series …
