    Can someone help me out. How would you write a mathematical expression for the graph that is attached. f(t) = ? 0 < t < 2pi

    This has the form:

    y=a*t

    In this case, a=\frac{A}{T}

    You typed in that you need the functional expression over the interval from 0 to 2pi. The sawtooth waveform you provided the picture for has a period of 2. There's no simple way to write a single formula without using things like the unit step function (so as to be able to handle three discontinuities in that interval). Your interval could also be a typo, so you need to amend your post and make sure we know exactly what you want.

    It helps a great deal if you tell us what you're trying to accomplish or at least if you can describe a little about the context of your question.

    I think he wants to find the equation of the waveform shown from 0 to T as to find its fourier series.
