Ex 9.1, 11 - The degree of differential equation (d2y/dx2)3

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


Ex 9.1, 11 The degree of the differential equation ((๐‘‘^2 ๐‘ฆ)/(๐‘‘๐‘ฅ^2 ))^3+(๐‘‘๐‘ฆ/๐‘‘๐‘ฅ)^2+๐‘ ๐‘–๐‘›(๐‘‘๐‘ฆ/๐‘‘๐‘ฅ)+1=0 is (A) 3 (B) 2 (C) 1 (D) Not defined ((๐‘‘^2 ๐‘ฆ)/(๐‘‘๐‘ฅ^2 ))^3+(๐‘‘๐‘ฆ/๐‘‘๐‘ฅ)^2+๐‘ ๐‘–๐‘›(๐‘‘๐‘ฆ/๐‘‘๐‘ฅ)+1=0 (๐‘ฆ^โ€ฒโ€ฒ )^3+(๐‘ฆ^โ€ฒ )^2+sin (๐‘ฆ^โ€ฒ )+1=0 Since ๐‘ฆ^โ€ฒ is in sin (๐‘ฆ^โ€ฒ ) It is not a Polynomial equation โˆด Degree is Not Defined โˆด Option D is correct.
