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
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.
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?
