Question

Fourier series :

f(x) = { 1 ; -2 < x < 0
{ x ; 0 < x < 2

f(x + 4) = f(x)



Its neither EVEN nor ODD function

L = 2

My doubt ;

I got the answer for ;

ao = 2

bn = 1/n.pie [(-1)^n - 1]

an = (-1)^n + 2/(n.pie)^2 [(-1)^n -1]


It seems that the answer for "an" is incorrect .

Please help me to solve the "an" value .

Thanks .

Answer 1

when i checked the answer for "an" , it shows 2/(n.pie)^2 [(-1)^n -1] . So , the (-1)^n is missing in real answer . So , anyone please check whether my answer or real answer correct .
