## converting input in rlc circuits

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

 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.
