The hardest part is to understand how to calculate the $b_n$ coefficients via an odd extension of the initial condition. In many ways, this is somewhat backwards (usually we ask "How do I compute a Fourier series for an odd extension" | The hardest part is to understand how to calculate the $b_n$ coefficients via an odd extension of the initial condition.
