    Hi all, I need to find the frequency of this time domain.

    e(t) = 67.882 sin 2513 t.

    I got 67.882 divided by \sqrt[]{2} = 48V

    Frequency = 2513 divided by 2\Pi = 400 Hz

    Is this right?

    Thank you in advance!

    That's correct - 400Hz.

    In fact it doesn't matter if you just quote 2513 radians/sec - that's just as valid.
