EDIT: Problem found. This thread can now be ignored. 1. The problem statement, all variables and given/known data Find the indefinite integral. 2. Relevant equations ((y^2-1)/y)^2 dy 3. The attempt at a solution I've attempted a few things. I first attempted to split the statement inside the outer parentheses into two fractions; (y^2/y - 1/y)^2 dy Then to reduce it to, (y - 1/y)^2 dy And then foil it and take an antiderivative. This comes out to Foiled: y^2 - 2 + 1/y^2 dy And then the antiderivative: y^3/3 - 2y + 1/y + C But I appear to still be incorrect. According to Wolfram's integral calculator, the solution is y^3/3 - 2y - 1/y I'm close. I'm apparently missing a sign somewhere, and I can't seem to find where it is, and I don't feel comfortable plugging in the answer until I know how I got there.
