Hello,
Who can you solve this the problem is that I don't know who to bring in a standaard form
Who can help? Thanks.
I didn't. I looked at the problem for a while trying to see a way forwardOriginally Posted by ThePerfectHacker
short of brute force (that is getting out my copy of Piaggio or Kreysig).
After about 20 seconds it became obvious that the LHS (left hand side)
could be converted to a derivative by that change of variable, and "Bob
was my uncle".
I expect that I have seen this all before, and it is just subconscious memories
surfacing.
Variables separable is one of the simplest classes of ODE, I always checkWhich class of linear-equations it falls into? Or it that something you can up with yourself?
if something can be converted to one of these first (Its the only class,
other than linear constant coefficients, I can solve without having to
remind myself what to do next ).
