Chapter 9 Class 12 Differential Equations

Serial order wise

Last updated at Aug. 11, 2021 by Teachoo

Ex 9.2, 11 The number of arbitrary constants in the general solution of a differential equation of fourth order are : (A) 0 (B) 2 (C) 3 (D) 4 We know that Number of arbitrary Constants = Order of Differential Equation. Since Order = 4 β΄ Number of Constants =4 Thus, Option D is correct For Example A differential equation of fourth order is π¦^β²β²β²β²=1 And, its general solution is π¦=π₯^4/24+(π΄π₯^3)/6+(π΅π₯^2)/2+πΆπ₯+π· β΄ Number of Constants =4
