1. The problem statement, all variables and given/known data I put a triangle around the problem of interest. 2. Relevant equations 3. The attempt at a solution I solved for the eigenvalues, resulting in double-zero values. My question is, using the variation of parameters method, which is what (14) refers to in the question. How do I solve for the second zero. For the first I get the matrix () *c1 for the general solution. () Do I need to add a guess such as t to the next zero eigenvalue?
