FourierTrigSeries—Wolfram言語ドキュメント

WebWe can compute the Fourier Series for this function using the FourierTrigSeries command : FourierTrigSeries f, x, 5 1 2 2 Sin x 2 Sin 3x 3 2 Sin 5x 5 The structure of this command computes the Fourier trig function series for the function f, in terms of the variable x, up to the fifth order terms. WebFind a numerical approximation for a trigonometric Fourier series expansion of a function Contributed by: Wolfram Research ResourceFunction [ "NFourierTrigSeries"] [ expr, t, n] gives a numerical approximation to the nth-order Fourier trigonometric series expansion of expr in t. Details and Options Web1 How can I use Wolfram Alpha to compute the Fourier series (with real coefficients a 0, a n and b n )? (The 'Fourier series' command seems to summon the complex series) I.e. f ( x) = x + π for − π < x < 0 and f ( x) = π − x for 0 ≤ x < π ⇒ f ( x) ≈ π / 2 + 4 / π ( c o s x + 1 3 c o s 3 x + 1 5 c o s 5 x + ⋅ ⋅ ⋅) how to strengthen ankles for heels
