Options
- A2, 1
- B2, 3
- C1, 2
- D3, 2
Correct answer
B. 2, 3
Step-by-step solution
The given differential equation is 1 + 1 ( dy dx )^2 = ( d^2y dx^2 )^ 3 2 Squaring both sides to remove the fractional powers, we get: 1 + 1 ( dy dx )^2 = ( d^2y dx^2 )^3 Multiplying the entire equation by ( dy dx )^2 to express it as a polynomial in derivatives: ( dy dx )^2 + 1 = ( dy dx )^2 ( d^2y dx^2 )^3 The highest order derivative present in the equation is d^2y dx^2 , which means the order of the differential equation is 2 . The power of the highest order derivative in this polynomial form is 3 , which means
