I can't for the life of me understand how the book went from step A to step B--even though I realize its just a pesky algebraic manipulation.
Step A
[tex] M(1,u) dx +N(1,u)[u dx+ x du] = 0 [/tex]
Step B
[tex] [M(1,u) + uN(1,u) ]dx + xN(1,u)du = 0[/tex]
Step A to Step B? I tried factoring and tinkering around here and there but all was in vain.
