Complex numbers are crucial in ultrasound imaging to represent both the amplitude and phase of the sound waves used to create images of internal tissues and organs. Express the following complex numbers in polar form (reje with -π < 0 ≤ π). Z₁ = (1 + 2j)/(1 - 2j) Z₂ = (1 + j)ejπ/6 -) Demonstrate that the derivative of a sinusoidal function yields the same result when calculated using complex exponentials. Consider the waveform y(t)=sin(200лt + л/4) representing the signal driving an ultrasound transducer. First, calculate the time derivative of this waveform (dy/dt). Then, express y(t) in terms of complex exponentials and take the derivative. Did you obtain the same result?
