Find the phasor which represents the following sinusoidal current: i(t)= 6cos(t-1/2)A 4sin(t+/3)mA 3cos(t-3/8)A 2cos(t)-4sin(t)A 2.

1.Find the phasor which represents the following sinusoidal current: i(t)=
6cos(ωt-1/2)A
4sin(ωt+Π/3)mA
3cos(ωt-3Π/8)A
2cos(ωt)-4sin(ωt)A

2.Find the phasor which represents the following sinusoidal voltages: v(t)=
1/2cos(ωt-Π)V
7cos(2ωt+Π/2)mV
2sin(ωt-Π/7)KV
3sin(ωt)-cos(ωt)V

3.Transform the following voltage phasors to the standard form v(t)=Vmcos(ωt+ɸv)V:
Ṽ=
20e(jΠ/6)
5e(-jΠ/2)
3(1/2-j√3/2)
5+j7
All in votes.

4.Transform the following current phasors to the standard form i(t)=imcos(ωt+∅v)A:
