1.) Find fourier series of f(x)=4, x greater than -3 and less than 3
and
2.) Find fourier series of f(x) = x^2-x+3, x greater than -2 and less than 2
and
3.) Write the cosine and sine fourier series f(x)=x^2 for x greater than 0 and less than 2
Fourier Series and Cosine and Sine Fourier Series are found. The solution is detailed and well presented.
