I need to calculate the power factor of a single phase circuit which has a phase angle of 60 degrees between the current and the voltage. Can anyone help?????

If q is the phase angle between the current and voltage, then the power factor is equal to the cosine of the angle. I am not sure how to use the equation and dont really understand the question.
