Questions: What is the value of determine ES?

Solution Steps

The question seems to be incomplete or unclear. However, if we assume that the task is to determine the value of a mathematical expression or a determinant, we can outline a general approach for finding the determinant of a matrix, which is a common mathematical task.

1. Identify the Matrix: Determine the matrix for which the determinant needs to be calculated.
2. Use a Mathematical Library: Utilize a Python library such as NumPy to compute the determinant efficiently.

The matrix given is

$$\mathbf{A} = \begin{bmatrix} 1 & 2 \\ 3 & 4 \end{bmatrix}$$

To find the determinant of the matrix $\mathbf{A}$, we use the formula for a $2 \times 2$ matrix:

$$\text{det}(\mathbf{A}) = ad - bc$$

where $a = 1$, $b = 2$, $c = 3$, and $d = 4$. Thus, we have:

$$\text{det}(\mathbf{A}) = (1)(4) - (2)(3) = 4 - 6 = -2$$

The calculated determinant is

$$\text{det}(\mathbf{A}) = -2.0000$$
