The second order differential equation is

Directions: In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as Assertion (A): The order of the differential equation given by (dy)/(dx)+4y=sinx is 1. Reason (R): Since the order of a differential equation is defined as the order of the highest derivative occurring in the differential equation, i.e., for nth derivative (d^ny)/(dx^n) if n = 1.then it's order = 1. Given differential equation contains only (dy)/(dx) derivative with variables and constants.

Consider the following statements in respect of the differential equation (d^(2)y)/(dx^(2)) + cos ((dy)/(dx))=0 1. The degree of the differential equation is not defined. 2. The order of the differential equation is 2.
