Maths · Ordinary differential equations, their order and degree

The order, degree of the differential equation satisfying the relation \) \) is

The order, degree of the differential equation satisfying the relation \( \sqrt{1+x^{2}}+\sqrt{1+y^{2}}=\lambda(x \sqrt{1+y^{2}}) \) \( \left.y \sqrt{1}+x^{2}\right) \) is

  • A. 1,1
  • B. 2,
  • C. 3,2
  • D. 0,1

Step-by-step solution

The given relation simplifies to tan⁻¹x + tan⁻¹y = constant after trigonometric substitution. Differentiating gives y' = -(1+x²)/(1+y²), which is a first-order, first-degree differential equation. Thus order = 1 and degree = 1.
