The phasor technique makes it pretty easy to combine several sinusoidal functions into a single sinusoidal expression without using trigonometric identities. however, you cannot use the phasor technique in all cases. select the expressions below for which the phasor technique cannot be used to combine the sinusoids into a single expression.
check all that apply.
o 45 sin(2500t – 50°) + 20 cos(1500t +20°)
o 25 cos(50t + 160°) + 15 cos(50t +70°)
o 100 cos(500t +40°) + 50 sin(500t – 120°) – 120 cos(500t + 60°)
o -100 sin(10,000t +90°) + 40 sin(10, 100t – 80°) + 80 cos(10,000t)
o 75 cos(8t+40°) + 75 sin(8t+10°) – 75 cos(8t + 160°)
