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!
