Ex 9.1, 11 The degree of the differential equation ((๐^2 ๐ฆ)/(๐๐ฅ^2 ))^3+(๐๐ฆ/๐๐ฅ)^2+๐ ๐๐(๐๐ฆ/๐๐ฅ)+1=0 is (A) 3 (B) 2 (C) 1 (D) Not defined ((๐^2 ๐ฆ)/(๐๐ฅ^2 ))^3+(๐๐ฆ/๐๐ฅ)^2+๐ ๐๐(๐๐ฆ/๐๐ฅ)+1=0 (๐ฆ^โฒโฒ )^3+(๐ฆ^โฒ )^2+sin (๐ฆ^โฒ )+1=0 Since ๐ฆ^โฒ is in sin (๐ฆ^โฒ ) It is not a Polynomial equation โด Degree is Not Defined โด Option D is correct.
