    Hello manprash,

    Welcome to the forum.

    This function is a sinusoidal one rather than a square wave function.

    It will have zero average value.

    It is the sum of two simple sinusoids each of which individually has a zero average.

    The function you have entered is not a square wave

    The sum of two cosine waves of the same frequency is another cosine wave of the same frequency

    In general the average value is 1/(b-a)∫^{b}_{a}f(x)dx

    You need to define the limits of the integral as that also determines the
    average value as much as the function itself

    This looks like a maths problem to me
