| Suppose, ?, y and z are three basic independent variables. x is a variable which is a linear function of ?. p is another variable which is a function of ? and z, but not y, and the expression of p in terms of ? and z is not known. 1. How... |
| Say [x,y,z] and [r,?,z] represents Cartesian and Cylindrical co-ordinate system. Hence x & y both are functions of (r,?). Let p is function of (x, z) only and D[p, y] = 0. How should I represent them in sequence? If I write p = Function[{x,... |
