Ex 9.1, 1 - Determine order and degree of differential equations - Ex 9.1

  1. Chapter 9 Class 12 Differential Equations
  2. Serial order wise


Ex 9.1, 1 Determine order and degree (if defined) of differential equations. d4y/dx4 + sin (y''') = 0 d4y/dx4 + sin (y''') = 0 y'''+sin (y''') = 0 Highest Order of Derivative =4 ∴ Order =πŸ’ Degree :- Since yβ€²β€²β€² is in 𝑠𝑖𝑛 (y''') It is not a polynomial equation in derivative ∴ Degree Is Not Defined
