o sin 20 = cos ____​

Answer 1

10. On taking Laplace transform of differential equation

dt"

+ 4y(t) = sin t, with

y(0) = 0, y'(0) = 0, the subsidiary equation is (s? + 4) Y(s) =

Y(S)=+1)

The solution of

differential equation is

(2)

(A) y(t):

1/3

sin t

his

sin 2t

(B) y(t) =

yt) = ; (cost-Źcos 21

(D) y(t) = 1 (sin t + sin 26)

1

(C) y(t) = ž (cos t + cos 2t)
