Ex 9.1, 11 The degree of the differential equation (d2y/dx2)3 + (dy/dx)2 + sin (dy / dx) + 1 = 0 is (A) 3 (B) 2 (C) 1 (D) Not defined (d2y/dx2)3 + (dy/dx)2 + sin (dy / dx) + 1 = 0 (y")3 + (y')2 + sin (y') + 1 = 0 Since y' is in sin y' It is not a Polynomial equation in derivative Degree is not Defined Option D is correct.
