    Question Need Help in Fourier Transformation

    I have been trying to find equation for:
    1. Square wave
    2. Triangle wave
    3. Sawtooth wave
    using the Fourier transformation.
    The results i have got involve the infinite series using only sine terms. However i wanted to know whether it is possible to express the same using cos terms?
    If not then why?

    To have a Fourier series consisting only of cosines requires that the function be even (on the interval [-L,L], or extended to an even function)
