Solve the following equations:

Given Differential equation is:



……(1)


Homogeneous equation: A equation is said to be homogeneous if f(zx,zy) = znf(x,y) (where n is the order of the homogeneous equation).


Let us assume






f(zx,zy) = z0f(x,y)


So, given differential equation is a homogeneous differential equation.


We need a substitution to solve this type of linear equation and the substitution is y = vx.


Let us substitute this in (1)



We know that






Bringing like variables on same side we get,





We know that:


and


Also,



Integrating on both sides, we get,




( log C is an arbitrary constant)



( alogx = logxa)



( loga + logb = logab)


Since y = vx,


we get,






Applying exponential on both sides we get,




The solution of the Differential equation is
