I was wondering how to convert E=70.7sinwt..< (just an example)
to something like 50∠0 degrees?

Hi VerdictGuilty,
E=70.7sin(Ѡt + 10°) =70.7∠10° Too easy! ☺

You're converting it to phasor representation. You want to employ Euler's identity to convert the sinusoid to a complex number from which you can obtain the modulus(magnitude) and phase.

@NascentOxygen,
Since the phase angle is based on the cosine function, are you missing a 90deg factor in your answer? should it be 70.7∠80?
