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
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 sides, we get
log secv – logv = 2logkx
The required solution of the differential equation.
