1. The problem statement, all variables and given/known data Perform a partial fractions expansion of 1/(n(n+1))=a/n + b/(n+1) in order to find a function that represents x^n/(n(n+1)). 2. Relevant equations 3. The attempt at a solution so i broke up the partial fraction to 1/n -1(1+n). I integrate both to get ln(n) + ln(1-(-n)).. From there i am beyond lost Its number six on the attached worksheet.
