Lista de Exercícios de Análise de Fourier
=========================================

Calcule as Séries de Fourier para as seguintes funções:

[1] f(x)=abs(x), x=[-2,2] (função "dente de serra")

[2] f(x)=x^3, x=[-2,2] 

[3] f(x)=x^3-2x^2+3x-4, x=[-2,2]

[4] f(x)=exp(-x), x=[-1,1]

[5] f(x)=xcos(x), x=[-4,4]

[6] f(x)=(x^2+1)sin(2x)+cos(x), x=[-2,2]

Para saber se a resposta está correta, faça um gráfico superpondo a função original e a expansão.
