1. The problem statement, all variables and given/known data Evaluate each improper integral whenever it is convergent. 1. S 1-infinity 4 / x 2. S 4 - infinity 2/x^3/2 2. Relevant equations 3. The attempt at a solution I'm having trouble with antiderivatives. I understand how to do them when the problem is like x^4 + x^2 + 3 or something but anytime they're in like a fraction form I get lost and the first step in improper integrals is finding the antiderivative.
