QUESTION THREE 3 Consider the third order ordinary differential equation \frac{d^3x}{dt^3} - 2\frac{d^2x}{dt^2} - \frac{dx}{dt} + 2x = 0, where $x(0) = 0$, $\frac{dx}{dt}(0) = 1$ and $\frac{d^2x}{dt^2}(0) = 1$. (a) Convert the ordinary differential equation into a system of three first order linear ordinary differential equation. [5 Marks] (b) Write the system of equations in the vector-matrix form $\frac{dx}{dt} = Ax$. [5 Marks] (c) Use the fundamental matrix solution technique to solve the system of ordinary differential equation. [15 Marks] (d) Hence write down a solution to the original third order equation.
