Find the Fourier Series for the function on inverval (-pi,pi) f(x) = 1-sin(x) + 3cos(2x)
Find the Fourier Series for the function on inverval (-pi,pi)
f(x) = 1-sin(x) + 3cos(2x)
Homework Answers
The idea of fourier series is to expand every periodic function as a series involving sine and cosine terms... given any function involving constants,sines and cosines only (not higher powers e.g sin2x etc), it is itself a Fourier series in (-pi,pi)
