Hi
Would you help me to tell about integrating factor
Post a specific problem and we can show you.
Also, you can Google it and find plenty.
But here is an explanation:
Sometimes we can't separate variables, so we can use the integrating factor that Euler developed.
A first-order DE is called linear if we can write it as... [1]
Where p(x) and q(x) may be constants.
We can make the observation that if we defineby
, then
Therefore:
... [2]
If we multiply [1] through by, and then simplify using [2], we get:
This can be solved by integrating both sides to get:
There ya' go. A general explanation. If you want a specific example, please post a problem you are having trouble with and I can try to guide you through it. Okey-doke?
It's not as bad as it looks.
