NDA Math Differential Equation

Concept:
Order of a differential equation is the highest order of derivative that occurs in the differential equation.
Degree of a differential equation is the highest power of the highest order derivative that occurs in the equation, after all the derivativesare converted into rational and radical free form. Calculation:
Getting rid of the radicals by raising both the sides to power 2 will give us:
x2=1+‌

d2y

dx2

The highest derivative in it is ‌

d2y

dx2

, thereforeits order is 2 .
And, the highest power of this derivative in the equation is 1, therefore its degree is 1.
