Suppose a particle is moving in a planar force field and its position vector x satisfies \acute{x} = Ax and x(0) = x_{0} , where
A = \left [ \begin{matrix} 4 & -5 \\ -2 & 1 \end{matrix} \right ] , x_{0} = \left [ \begin{matrix} 2.9 \\ 2.6 \end{matrix} \right ]
Solve this initial value problem for t ≥ 0, and sketch the trajectory of the particle.
