The order of the differential equation (d2y/dx2) + 2(dy/dx)+ sinx = 5 is-
Answer & explanation
Correct answer: option 2
The order of a differential equation is equal to the highest order derivative involved in differential equation so in given differential equation
(d2y/dx2) + 2(dy/dx)+ sinx = 5
the highest derivative is of order 2 so the order of given differential equation is 2.
