    I the RMS over all time of a periodic function is equal to the RMS of one period of the function.

    Try this :
    1. Integrate the square of the function (that you got) over one period. This gives you mean square value.
    2. Under root of this is RMS.

    Put the limits from 0 to 1 to get 58.3333

    √(58.3333) =7.63
