Hi guys, I've got this differential equation:
And I've worked out the general solution when it is set equal to zero to be:
I need help finding the equation to set y(x) to so that i can solve the rest of it. Any clues?
Thanks in advance
The informal answer is that it's the simplest form that works .....
obviously is no good so try the next simplest: .
That doesn't work so try the next simplest: . That works so it's all you need. Consider it a rule of thumb.
There is a way of getting it formally but I don't have the time to type out the details right now. Chris likes D.E.'s ... he might get a kick out of doing it.
Thanks again,
I handed my work in and it all looks good, however some of my friends said that they did it by using the form .
You said here that that form wouldn't work and to move on to the next form up, so out of interest when I got home I tried it with form: and lo and behold I got the same answer as with form: .
Does that mean I did something wrong?
Cheers,
