Web3. We are asked to find the fundamental matrix for the two-dimensional system defined by: (1) x 1 ′ = x 1 + t x 2. (2) x 2 ′ = x 2. And determine the solution for which x 1 ( 0) = c 1, and x 2 ( 0) = c 2. We note that these equations are both first-order linear and are decoupled. We are going to use this to our advantage, by solving for x 2 ...
