Calculate the magnitudes and phases of the phasor representations of the following quantities:
(i) i₁(t) = Iₛ cos(ωt + 0.5)
(ii) v₂(t) = Vₛ sin(ωt - 1.2)
(iii) Z₃(ω) = R + jωL
(iv) Z₄(ω) = R/(1 + jωCR)
where f = (1000 + β) kHz, Iₛ = (100 + α) μA, Vₛ = (2500 + δ) mV, R = (1800 + ε) Ω, L = (2200 + λ) μH, C = (470 + η) pF.
