WebFourier series date at least as far back as Ptolemy's epicyclic astronomy. Adding more eccentrics and epicycles, akin to adding more terms to a Fourier series, one can account for any continuous motion of an object in the sky. – Geremia Jan 11, 2016 at 2:56 Add a comment 8 Answers Sorted by: 158 Web200 years ago, Fourier startled the mathematicians in France by suggesting that any function S(x) with those properties could be expressed as an inﬁnite series of sines. … dance schools looking for teachers

WebMar 24, 2024 · Fourier series make use of the orthogonality relationships of the sine and cosine functions. The computation and study of Fourier series is known as harmonic … WebFeb 9, 2015 · A trick that lets you determine the coefficients very easily is to take the inner product of both sides with v j : x, v j = ∑ i = 1 N c i v i, v j = ∑ i = 1 N c i v i, v j = c j. (Notice that in the last step, all but one of the terms vanishes, which is awesome.) So we have discovered that. c j = x, v j . Web4.1 Fourier Series for Periodic Functions 321 Example 2 Find the cosine coeﬃcients of the ramp RR(x) and the up-down UD(x). Solution The simplest way is to start with the sine series for the square wave: SW(x)= 4 π sinx 1 + sin3x 3 + sin5x 5 + sin7x 7 +···.
