2. Given the following functions X₁ (t) = X2 (1) = 11 cos (10t + 3/8) 3 cos (10t - ¹/2) a) Compute the respective phasors, X₁ and X₂ . b)

Calculate x3 (t) = x₁ (t) + x₂ (t) using the phasor addition rule. c) Plot x₁ (t), x₂ (t), and x3 (t) all on the same plot using Matlab. d) Use the plots in part (c) to verify your answer from part (b).
