    So l just need to be pointed in the right direction and the rest l will do myself. How do l get the amplitude and phase for ω=2t. There is a sine and cosine with ω=2t. How do l deal with them.

    I do understand how to get the Fourier series. The given signal is a already a calculated fourier series they just want it to sketch its Fourier spectra. I am confused on what to do at ω=2t

    You probably meant to say at ω=2.

    The amplitude would be the square-root of the sum of squares:

    <br /> \sqrt{(\sqrt{3})^2 + 1^2} = \sqrt{4} = 2<br />

    See if you can figure out the phase on your own.

    And the phase is 30 degrees. I now get it. Thanks man.

    Well the phase angle is either 30 or 60 degrees. Try to figure out which is the correct answer.
