WebThis series is called the trigonometric Fourier series, or simply the Fourier series, of f (t). The a’s and b’s are called the Fourier coefficients and depend, of course, on f (t). The coefficients may be determined rather easily by the … 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. This …

Note: If the function is even {f(t) = f(-t)} , the series expansion will only contain cosine terms whereas in the case of an odd function {f(t) = -f(-t)} , the expansion will only contain sine terms. churkey changa
