Hi,
I am trying to learn partial diff equations myself and I'm stuck with this small step which I do not understand. I hope someone will help me.
Question:
Solve the PDE
Solution:
Subsidiary equations are
The step which I do not understand is this :
Using multipliers x, y, z. we get:
each fraction=
Rest of the solution I understand but I don't get that how they did this particular step.
Thanks for your time and effort
