    Can This Linear System Be Considered Stable?

    Ah, so it has a transfer function of one! I didn't think that it would be that easy. This also means that is stable (poles at zero) so I think we are all set. Thanks again!

    Can This Linear System Be Considered Stable?

    I had a feeling this was a strange question which doesn't help since I don't fully understand how to obtain transfer functions in the first place. So applying the time shift 0.5X(n) + z^{-2}100X(z) -20z^{-10}(z) Collect the X(z)'s This transform is from the time shift right? X(z)= 0.5 +...

    Volume of rotation - my answer seems off a bit

    Find the area of the given function, rotated about the y axis The Area below the line y=2 and above y=sin(x) from 0-\pi I did this rotated around the X AXIS no problem, I found the area of the disk to be \pi(4-sin^{2}(x)) The volume around the X AXIS to...
