The following signal is a sum of sinusoids that can be simplified and expressed as a single sinusoid of the form: A cos(ot + o), where all phases are in radians. V2 cos(64t - 45) - V3 cos(6nt - 60) + 15 cos(60t - 90) <. In the two boxes, give numerical answers for the amplitude A and phase o in radians such that -1 < • The answer should be numeric, with 3 or more significant digits. • Either fixed or exponential notation (e.g. 0.0015 or 1.5e-3) is acceptable. • An answer with pi such as 9*pi, will NOT be accepted; a number must be entered. • An answer for the phase should lie in the range BETWEEN -and , i.e., (-1,1].
