In each of the question, show that the given differential equation is homogeneous and solve each of them.
Here, putting x= kx and y = ky
= k0.f(x,y)
Therefore, the given differential equation is homogeneous.
To solve it we make the substitution.
y = vx
Differentiating eq. with respect to x, we get
Integrating both side, we get
log(cosecv – cotv) = -logx + logC
The required solution of the differential equation.
