Given the following phasors and the information related to the frequency of that phasor, provide the corresponding time-domain representation. (It is somewhat hard to tell the difference, but the terms on the left are the symbols for the phasor, e. g., V, while the terms in the interior provide the units, e. g., V is volts.) (a) V = 7e jπ/6 V, ω = 100 rad/s (b) V = √ 2e −j0.25 V, f = 100 Hz (c) V = 42 π/6 V, T = 10−6 s (d) I = 17 45◦ A, ω = 2π2 × 103 rad/s (e) I = 7 −π/2 A, f = 0.5 Hz
