 Author Comment/Response Miles 02/05/12 6:51pm Hello, I am trying to convert the following (example) expression: Cos[\[Phi]]*Sin[\[Theta]]^2*Sin[\[Phi]] To cartesian coordinates using the following rules: shToCartesian = {Cos[\[Theta]] -> z, Sin[\[Phi]] Sin[\[Theta]] -> y, Cos[\[Phi]] Sin[\[Theta]] -> x} But applying it as follows: Cos[\[Phi]]*Sin[\[Theta]]^2*Sin[\[Phi]] //. shToCartesian Does not perform any replacements: Out := Cos[\[Phi]] Sin[\[Theta]]^2 Sin[\[Phi]] Whereas the expected answer is: Out := xy Is there a way to coax Mathematics to perform this transformation? Cheers, Miles URL: ,
