The problem I'm doing asks me to solve the normal system x'=Ax, but A is an unknown 2x2 matrix. However, I'm given some initial values and:
OK, I know this says -4 is an eigenvalue with corresponding eigenvector (-1,4)
But I'm not sure what to make of this.
My current approach is to find so I need a second, maybe generalized? eigenvector and corresponding eigenvalue.
edit: Never mind, I figured I can just solve for A
