    2. Relevant equations

    I don't understand how they get the inequalities in their solutions as well as the limits for the integral. (look at the red boxes)

    3. The attempt at a solution

    I understand that they calculated the jacobian and every step. I just get stuck at the integral part as well as how they obtained u≥1. In the question it says x and y are both ≥ 1
