Determine an expression for the natural solution for v (t) . c) Find and plot v (t) for t &gt;0 if v s (t)=5u(t) V. (Use your best judgement for plot axes. Plot using Matlab, Excel, or other software.) d) Determine the forced solution for v (t) for t&gt;0 if v s (t) = 2 cos(10 7 t) u(t) V by inserting a trial solution of the form A cos(10 7 t) + B sin(10 7 t) into the differential equation from a). (and determine the values for coefficients A and B). e) Determine the forced solution for v (t) for t&gt;0 if v s (t) = 2 cos(10 7 t) u(t) V using phasors (frequency domain). f) Determine the complete solution for v (t) for t&gt;0. Using Matlab, separately plot the natural solution, forced solution, and complete solution for v (t) . C v s (t) R 2 L R 1 v +i Ki R 1 =10k R 2 =1k C =2nF L =1mH K =0.3...
