The order of the differential equation $\left[1+\left(\frac{d y}{d x}\right)^2\right]^2=\left(\frac{d^3 y}{d x^3}\right)$ is :
Answer & explanation
Correct answer: option 1
$\left(1+\left(\frac{d y}{d x}\right)^2\right)^2=\frac{d^3 y}{d x^3}$
for given differential equation highest order derivative is differentiated thrice
So order = 3
