Matrix Equations and Differential Systems

The video tutorial explains how to write a system of differential equations in matrix form. It begins by introducing the concept and initial conditions, then moves on to formulating the vector and matrix valued functions. The tutorial details the construction of the matrix for the system of equations and concludes with applying initial conditions and summarizing the process.

What are the initial conditions given for the system of differential equations?

• X1(0) = 4 and X2(0) = -2

• X1(3) = -2 and X2(3) = 4
