The Attempt at a Solution
Using superposition, considering only the varying voltage source.
Z (L) = 4j
Z (C) = 5j
Total impedance:
4 is parallel with 5 = 2.44 + 1.95j
series with 1 + 4j
Total impedance: 3.44 + 5.95j = 6.87 <60°
Voltage source: 10<0°
Voltage division Vo(t) = 10<0° * (1/(6.87 <60°)) = 1.45<-60°
= 1.45cos (2t - 60°)
However this is off from the cos part of the correct answer.
What's wrong with my working?
Thank you very much.
