any help on this one: if you type in: v3/Sqrt[v1^2]/Sqrt[v2^2] - v3/v1/v2 you get the same expression Even if you then type Simplify[%] you still get the same expression I would have thought Mathematica would have resolved Sqrt[v1^2] to v1 (!?) Does anyone out there know why it does not do this, as it is causing some problems with some proofs I am doing ?
