1. The problem statement, all variables and given/known data Evaluate the definite integral of the algebraic function. Use a graphing utility to verify your result. Integral from [1 to 2] of (3/x^2 - 1) 2. Relevant equations The answer is 1/2 f(x)dx= F(b) - F(a) 3. The attempt at a solution I tried taking it to make it -x^-3 - 1x as the antiderivative but when I put 2 in and then 1 I don't get the answer.
