In this section we will learn how Fourier series (real and complex) can be used to sine can be written as the sum and difference of two complex exponentials:

In this section we will learn how Fourier series (real and complex) can be To derive these we write ei(A±B) = eiAe±iB
Fourier series is used to get frequency spectrum of a time-domain signal when signal is a periodic function By using complex exponential Fourier series.
In words shifting a signal in the time domain causes the Fourier transform to be multiplied by a complex exponential. Incidentally
