Please answer the following question showing steps and full details and thank you.

Let x and y be functions of the variable t and suppose that they satisfy the coupled differential equations

x ? + 2 y = cos t

y ? ? 2 x = sin t ,

where x? and y? denote the derivatives of x and y with respect to t, and x(0)= y(0)=0.

Set L[x]=u and L[y]=v, where L denotes the Laplace transform. Let s denote the usual variable in the transform space.

1) What equations do u and v satisfy?

2) What is the solutions u and v of the system of equtions in question 1)?

3) Using u and v from Question 2), determine the solutions x(t), y(t) of the coupled differential equations from Question 1).

2) What is the solutions u and v of the system of equtions in question 1)?

3) Using u and v from Question 2), determine the solutions x(t), y(t) of the coupled differential equations from Question 1).
