Final answer:
To write the vector equation as a matrix equation, we can express the vector à in terms of its components Ax, Ay, and Az. We can then write the equation in matrix form by separating the scalar components and the unit vectors.
Step-by-step explanation:
To write the vector equation as a matrix equation using the definition of Ax, we need to express the vector à in terms of its components Ax, Ay, and Az.
According to Equation 2.10 and Equation 2.11, vector à can be written as:
à = AxÎ + AyĴ + Azâ
We can rewrite this equation in matrix form by separating the scalar components and the unit vectors:
à = [Ax, Ay, Az]
This is the matrix equation representation of the vector equation using the definition of Ax.
