Partial fraction decomposition

  1. Mar 29, 2012 #1
    1. The problem statement, all variables and given/known data

    [tex] \frac{2e^3}{((s^2)-6s+9)*s^3} [/tex]

    you can factorize the denominator into s,s,s,(s-3),(s-3)

    that gives you 5 residuals.

    the first 3 should all be the same value but that's apparently not correct, so where

    am I going wrong?

    Hi Ry122! :smile:
    Your denominators need to be s s2 s3 s-3 and (s-3)2 :wink:
