dy/dx + y/x \ x3y2
Solution: The given diffrential equation is --------(1) is first order first and degree diffrential equation.
This is of the form where is known as Bernoliie's diffrential equation.
Dividing equation (1) with , we get
--------(2)
-----------(3)
put
Equation (3) becomes
that implies ------(4)
This is of the form where
which is Linear diffrential Equation in 't'.
Integrating factor(I F )=
I F = =
Therefore Integrating factor ( I F ) =
The solution of (4) is given by ------(5)
------(6)
replace t by in (6)
we get
The solution of is .
