I have been working on a problem that requires me to integrate in the following way: $$\int_{0}^{\infty} \int_{0}^{y} \int_{0}^{yx} f(x,y,z)\ dzdxdy$$ I would like to change the order of integration, with dz going last. For the dydxdz option, I've got: $$\int_{0}^{\infty} \int_{0}^{\infty} \int_{x+z}^{\infty} f(x,y,z)\ dydxdz$$ Is this correct? And what would the dxdydz option look like? Thanks in advance for any help!
