Q7 of 118 Page 406

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 sides, we get




log secv – logv = 2logkx









The required solution of the differential equation.
