In these type of question, I just find the wronskian and W₁ and W₂ as this equation was second order and then find their respective U's, So for U₁ integrate the division of W₁ and W and for the U₂ integrate the division of W₂ and W. Then you multiply respective U's to your Y's in this case y₁ and y₂ then add it to your general solution. For a better understanding of this process, I would recommend seeing the example 1 of section 4.4 in the textbook. I think that will clarify how the integral was solved in this question.

when we find the eigenvector from the corresponding eigenvalues shouldn't the vectors be (i, 1)  and (-i, 1)?

When finding the general solution shouldn't the g(t) be coth(t) instead of cosh(t)?
