1. The problem statement, all variables and given/known data "Put each of the following into the form Acos(ωt+θ)..." (a.) 4ejt+4e-jt 2. Relevant equations Euler's Identity: ejθ = cos(θ)+jsin(θ) Phasor Analysis(?): Mcos(ωt+θ) ←→ Mejθ j = ej π/2 Trignometric Identities 3. The attempt at a solution I attempted to use phasor analysis to simply have it be 4cos(ωt)+4cos(ωt), however, the given problem doesn't seem to follow the same form as the "examples" for phasor analysis. I also attempt to use Euler's identity (thus changing it into the cos()+jsin() form) but that still confused me because the example given wth Euler's is for a ejθ not an ejt. I basically need a solid jump off point so I can correctly reason the answer out.
