I'm completely stumped on these. I don't know how to proceed once I get to the eigenvalue since my typical method for solving would be to set Ax=x , then solve. However, this would give me -5x1=-5x1 and -5x2=-5x2 which makes A trivial. I just realized that means the eigenvectors will be <1,0> and <0,1>, but I'm still stumped on parts b and c. Consider the following system. (A computer algebra system is recommended.) dx = -5 0x dt *...
