Hi

I got a couple of questions that i am having trouble with:

1)Use Laplace transform to solve the following initial value problems:

y(0) = 20 and y'(0) = 34

This is what i have done:

What should i do next??

2) Use Laplace transform to solve each system of differential equations

given x(0) = 1 y(0) = 0

This is what i have done

Matrix Form to solve X and Y

| s 1 |

| s -1 |

Det= -2s

| 1+cos(t) 1 |

| 1 -1 |

| s 1+cos(t) |

| s 1 |

what is wrong?

P.S
