Family of curves $y = Ax+ A^3 $ is represented by the differential equation of degree |
3 2 1 none of these |
3 |
The correct answer is option (1) : 3 We have, $y = Ax+ A^3 ⇒\frac{dy}{dx}= A$ On eliminating A, we get $y = x \frac{dy }{dx} + \left(\frac{dy}{dx}\right)^3$ Clearly, it is a differential equation of degree 3. |
