Hello, is there an easy way to get 'full' differentiation, ie, of all variables, instead of only the main variable? Example: Given symbols x,u, diff(x/u, x) would then produce (u-u'x)/u^2. At the moment, I'm abusing psi to get the effect but that is certainly not the best way. sincerely, ralf

You would need to define 'u' as a function. Bye, Christian -- / Physics is an algorithm \/ http://www.uni-mainz.de/~bauec002/
