What is the determinant of the matrix \( \begin{pmatrix} 1 & 0 & 0 \\ 0 & 1 & 0 \\ 0 & 0 & 1 \end{pmatrix} \)?
Step 1: Identify the matrix given in the question. It is a 3x3 matrix: \( \begin{pmatrix} 1 & 0 & 0 \\ 0 & 1 & 0 \\ 0 & 0 & 1 \end{pmatrix} \).
Step 2: Recognize that this matrix is called the identity matrix. The identity matrix has 1s on the diagonal (from the top left to the bottom right) and 0s everywhere else.
Step 3: Understand that the determinant is a special number that can be calculated from a matrix. For the identity matrix, the determinant is always 1.
Step 4: Conclude that the determinant of the given matrix is 1.
