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!
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 +...
Homework Statement

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...
