Dear all, 1.) How to find the General Solution for below's partial differential equation? (y + u) du/dx + y (du/dy) = x - y ** I use "d" to represent the partial differential symbol. Can it be solved by function NDSolve in mathematica 4.1? How? 2.) I manage to get the roots of complex equation z^5 = i from Solve[z^5 == i, z]. It gave me straight the 5 roots in the output. Is there any way to view the steps in mathematica? Thanks a lot!
