AC wave form question

  1. Oct 24, 2015 #1
    Hello everyone

    I would like to ask a question that seems simple but cant find the (detailed) proof/ how its derived.
    Simply we know that Vrms = Vpk /[Sqrt (2)]. But how is that derived?

    Thank you in advance

    That is only correct for a true sine wave.
