Part a – c in photo
(d) For the rest of the problem we change Vin to 10V. Solve the linear circuit with the Thevenin as defined by Vin = 10V, and the diode linearized to vD0 = 0.63 V to determine
(e) If vD1 changes substantially from vD0, rederive a linearized model like you did in part (b), and iterate with the Thevenin equivalent assuming Vin = 10V to get vD2
(f) Repeat to solve for the voltage across the diode to 3 significant figures.
