Verify by substitution that each given function is a solution of the given differential equation. Throughout these problems, primes denote derivatives with respect to x. y^''+4 y=0 ; y1=cos2 x, y2=sin2 x | Numerade

SOLVED:Use (12) to verify that the indicated function is a solution of the given differential equation. Assume an appropriate interval I of definition of each solution. x (d y)/(d x)-3 x y=1 ; y=e^3 x ∫1^x (e^-3 t)/(t) d t

Verify that the given function (explicit or implicit) is a solution of the corresponding differential equation: x y = tan–1y : y2 y′ y2 1 = 0 - Mathematics | Shaalaa.com
