The general solution of the linear system \(\dot{\vec{x}} = A\vec{x}\) is

\[
\vec{x}(t) = 
\begin{bmatrix}
e^{t/4} & 0 \\
0 & e^{t/3}
\end{bmatrix}
\begin{bmatrix}
c_1 \\
c_2
\end{bmatrix}.
\]

Determine the constant coefficient matrix \(A\).

\[
A = 
\begin{bmatrix}
\boxed{\phantom{x}} & \boxed{\phantom{x}} \\
\boxed{\phantom{x}} & \boxed{\phantom{x}}
\end{bmatrix}
\]
