Original Message (ID '142895') By Nasser M. Abbasi:
(below same replay I gave on sci.math.symbolic) You mean something like this (in 2D space) ----------------------------- r = {Cos[t], Sin[t]}; b = {1, 2}; f = (r + b)/Norm[r + b]; D[f, t] --------------------------- ps. it is not good idea to use single UpperCase variables in Mathematica. Also, variable names and functions names should start with lowerCase letters. --Nasser
