Homework Statement Consider a discrete-time system, driven by: x[k+1] = Ax[k] for non-zero inital conditions x[0] a) write the closed-form solution of x[k]. If the system is asymptotically stable how should x(k) behave? b) what is condition for asymptotic stability? Homework Equations...

So I am a 3rd year physical science major at my university with a strong interest in EE. I would rather be an EE major but things happened, didn't get into the school. blah. My question(s): 1) I am trying to load my transcript with classes that will look well to employers and grad schools (for...

Still stuck. Here's what I did with Gauss' Law in mind. (btw, the answer is (2pi\epsilon)/ln(R2/R1) and that's not pi to the epsilon not power btw.) So, with Gauss, you have integral of E dot dA which equals Q/\epsilon. Capacitance - Q=VC...so subsitute that back into the gauss equation so...
