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.
