Describe the quadrant of the complex plane, in which the complex number is located. 3.(a) A continuous-time sine wave has a frequency of 60 Hz, an amplitude of 117 V, and an initial phase of u03c0/4 radians. Describe this signal in a mathematical form using the Sin function. 4. A sinusoidal signal described by 50 Cos (20u03c0t u03c0/4) passes through a linear time invariant (LTI) system that applies a gain of 1.5 and a phase lag of u03c0/2 radians to the signal. Write
