Problem 7.27 Use phasors to simplify each of the following expressions into a single term (*hint: see Problem 7.26): (a) v₁(t) = 12 cos (6t+30°) − 6 cos (6t – 45°) (b) v₂ (t) = -3 sin(1000t – 15°) - 6 sin(1000t +15°) + 12 cos (1000t - 60°) (c) v3 (t) = 2 cos (377t +60°) — 2 cos(377t – 60°) (d) V4 (t) = 10 cos 800t + 10 sin 800t
