matrix inversion with complex numbers?? or faster way?
i managed to get the answer, but it took me like 30min. to work this by hand. i probably worked it differently than my instructor's method above, but wat i did was get the coefficients of V on one side, coefficient of V(ex) on the other side.
(3/0.2 + 1/(0.1+j0.1))V = (1/(0.1+j0.1))Vex
(20-5j)V = (5-5j)Vex
V=((5-5j)/(20-5j))Vex
V=(0.343<-30.96)Vex
which in fact did equal V=[0.294− j0.176]Vex when i converted to rectangular form. the problem is, this took me way too long to work, i was wondering if there was an easier way. like perhaps matrix inversion with complex numbers? i still have no idea how that works. because i have a test on this and if i spend 30min. to simplify equation like this, and plus this isn't even the answer to the problem, it's just one equation. is there an easier way??
