Homework Statement


Two sinusoidal voltages with amplitude 15Volts and frequency 2,771Hz are separated in time by 68% of a period. What is the phase shift in degrees between the two signals?

Homework Equations


y= Asin(omega)(x-h)

The Attempt at a Solution


I know my A is 15 and I'm pretty sure that my omega is 2771. I am confused, however, as to what I should put for my period. Should I put (2pi)*.68, but then what how could I get a numerical answer out of all of that?

(2pi)*.68
How many degrees is that? :smile:

That's 244.8 degrees if I multiply 360 by 2pi. So would this number be my phase shift?

The answer is what I get also, but you have a typo in your reply which I have fixed. :smile:
