Homework Statement
For a phasor V(x) = 8 + 4j find the sinusoidal signal that it represents if the frequency is 50 Hz?

The Attempt at a Solution
sqrt(64+16)=8.944sin(50t) so clearly this is not correct?
where ω=2(pi)f=100(pi) and sin(ωt+θ) I found θ by tan^-1(4/8)=26.56°
Yup. That'll do it. Although strictly speaking you should indicate the units of the arguments to the sin function, since one is clearly radians and the other degrees...8.944sin(100∏t+26.56)
