1. The problem statement, all variables and given/known data Evaluate the integral. (Remember to use ln |u| where appropriate.) ∫ds/s^2(s − 1)^2 2. Relevant equations 3. The attempt at a solution I attempted a solution using the method of partial fractions, but it seems my answer is wrong. Here's what I did... 1=A/s +B/s^2+C/(s-1)+D/(s-1)^2 Then multiplying by a common denominator, 1=As(s-1)^2 +B(s-1)^2 +Cs^2(s-1) + Ds^2 1=A(s^3-2s^2+s) + B(s^2 - 2s +1) + C(s^3 -s^2) +Ds^2 Equating the coefficients and solving for A, B, C, and D, I get A=1, B=1, C=-1, D=3 So my integral now looks like ∫1/s+1/s^2-1/(s-1)+3/(s-1)^2 And taking the integral, I got lns - 1/s - ln(s-1) + 3/(s-1) which evidently is wrong. If anyone can point me in the right direction in terms of where I went wrong, it would be greatly appreciated. Thanks!
