Find all the poles and multiplicities of
a)
b)
Attempt:
a) ok so
Would that mean pole at z= -3 of order 2 or order 6?
b)
So there is a pole at z=-3 of order 1 but is the pole at z=-2 of order 1 or order 2?

For part a) this should help
has pole of order 4. What's the order of the pole of this
?
For part b) you are not done. What's the definition of pole? Does your function look like the definition in its current form? I mean, what you have is right but it's more technically correct to write it all out as a fraction of polynomials.
thats what i was asking :P
We have covered the first example you showed, but not where the whole fraction is raised to a power. My feeling is that it would also be 4 because they are equivalent.
oh so for part b, 7z+3/ (z+2)(z+3) and then pole at z= -2,-3 both of order 1?
Thanks for the speedy reply
