 P: 1 I was wondering how to convert E=70.7sinwt..<-- (just an example) to something like 50∠0 degrees?
 HW Helper P: 4,192 Hi VerdictGuilty, E=70.7sin(Ѡt + 10°) =70.7∠10° Too easy! ☺
 P: 36 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?

I referenced it to a sine wave.
