Question $1-)$ For the circuit shown below $V_s=6V,$ IS $1=3A,$ IS $2=0\mathrm{.}08cos(5t),V2=2i_2^2+4i_1{V}_l,i=V\frac{1}{8}-V\frac{2}{8}$

a$)$ Find the operating points of V$1,$ il$,$ V$2,$ i$2.($Take the positive root as the solution of the second degree equation$).$

b$)$ Make small signal analysis and approximate solutions $V_n(t)=V_{nQ}+v_n(t)$ and $i{n}_n(t)=$InQ$+in(t)(n=1,2)$
