Two oscillating sinusoidal voltage signals v₁ and v₂ of amplitude 2 V and 1 V, respectively, at a frozen instant in time are represented by the V 1 following complex numbers in Cartesian form (to 2 d.p. in Volts), v₁ = 1 + 1.73 j, 1 v₂=-0.22 - 0.97 j. Calculate the phase angle in radians between the two signals (in the counterclockwise sense from v 1 to v 2 to 2 d.p.). 3.44
