A) 2, 1
B) 1, 2
C) 3, 2
D) 2, 3
Correct Answer: B
Solution :
General equation of parabola whose axis is X-axis, is \[{{y}^{2}}=4a(x+h)\] On differentiating w.r.t. x, we get \[2y\frac{dy}{dx}=4a\] \[\Rightarrow \] \[y=\frac{dy}{dx}=2a\] Again, differentiating w.r.t. x, we get \[y{{\left( \frac{dy}{dx} \right)}^{2}}+y\frac{{{d}^{2}}y}{d{{x}^{2}}}=0\] This is a differential equation whose degree and order are 1 and 2, respectively.You need to login to perform this action.
