Re: polynomial decomposition

Hey niaren.

Are you allowed to go from partial fraction decomposition back to original decomposition or must you go from original to partial?

In a lot of proofs, people actually do the reverse if they can't do the original method.

Re: polynomial decomposition

Hi chiro, thanks for your reply. In going from $\displaystyle H_1$ to $\displaystyle H_2$ another guy told me it could be done by partial fraction decomposition. He said it was easy but tedious. He is quite experienced so I took his word for it. To start with I thought it sounded reasonable but now that I have look at it for some time I'm starting to doubt that going to $\displaystyle H_2$ is all that easy and moreover I doubt that going through partial fraction decomposition is maybe not more direct than some alternative method. So basically what I'm trying to find out is if there is some sequence of steps that can be applied starting from $\displaystyle H_1$ and have end result $\displaystyle H_2$.
