An integral paradox ??
let be [tex] \int_{0}^{\infty}xdx \int_{0}^{\infty}ydy [/tex]
changing to polar coordinates we get that the double integral above shoudl be
[tex] 2\int_{0}^{\infty}r^{3}dr [/tex]
althoguh they are all divergent , is this true can we ALWAYS make a change of variable to polar coordinates without any ambiguity ??
