Problem in the Differential equation [closed]

I have the following Differential equation which I need to solve:

$$\frac{\mathrm{d^2} y}{\mathrm{d} x^2} = \left(\frac{\mathrm{d} y}{\mathrm{d} x}\right)^2$$

I know how to solve a second order linear differential equations but this is something strange equation which I have seen before while practicing the Differential equation Chapter. Please tell me how to go about solving this Differential equation problem. Any intial hint would do for me.

Thanks

• let $v = \frac {dy}{dt}.$ Now you have a first order differential equation. $\frac {dv}{dt} = v^2$ – Doug M Apr 26 '18 at 3:05
• You should probably see how to solve non-linear differential equations and then come back to this one – Francisco José Letterio Apr 26 '18 at 3:15
• @DougM I understood your point. After solving, this gives $\frac{-1}{v}=t+c$ for the Differential equation $\frac{dv}{dt}=v^2$. Should we again substitute, the value of p into the Differential equation? – RAHUl JHa Apr 26 '18 at 3:28

Put $\frac{dy}{dx}$ = $v$, after differentiating w.r.to $x$ you get $\frac{dv}{dx}$ = $v^2$
then $\frac{-1}{v}$ = $x+C$
or, $v$ = $\frac{-1}{x+C}$
so $\frac{dy}{dx}$ = $\frac{-1}{x+C}$
$y$ = $-ln(x+C)$ + K
