How do you find the cosine series?
cos ( 1 + n ) π − 1 = cos ( 1 − n ) π − 1 = { − 2 if n is even 0 if n is odd . Thus, a n = 1 π [ ∫ 0 π sin ( 1 + n ) x d x + ∫ 0 π sin ( 1 − n ) x d x ] = 2 π ⋅ 1 + ( − 1 ) 2 1 − n 2 .

The Maclaurin series of cos(x) is the same as the Taylor series centered at 0, which can be written as 1 - (x^2)/2 + (x^4)/4 - (x^6)/6
What is cosine in Fourier series?
The Fourier series for an even function with period 2L is thus given by the Fourier cosine series f(x)=a02+∞∑n=1ancosnπxL,f(x) even. and the Fourier series for an odd function with period 2L is given by the Fourier sine series f(x)=∞∑n=1bnsinnπxL,f(x) odd.17 nov. 2021
