Program Explanation Given information: The differential equation is y ″ + 4 y = 0 and the function is y 1 = cos 2 x and y 2 = sin 2 x . Calculation: Label the given function as y 1 = cos 2 x ........ (1) Label the given function as y 2 = sin 2 x ........ (2) Label the given differential equation as y ″ + 4 y = 0 ........ (3) Differentiate equation (1) with respect to x as shown below: y ′ 1 = d d x ( cos 2 x ) = − 2 sin 2 x Again differentiate y ′ 1 = − 2 sin 2 x with respect to x as y ″ 1 = d d x ( − 2 sin 2 x ) = − 2 ( 2 ) cos 2 x = − 4 cos 2 x Substitute − 4 cos 2 x for y ″ and cos 2 x for y in the left-hand side ( L .H .S ) of the equation (3) as L .H .S = − 4 cos 2 x + 4 ( cos 2 x ) = − 4 cos 2 x − 4 cos 2 x = 0 Hence, the left-hand side and right-hand side of the differential equation is the same
