Problem

(I_2)

Solution

1. Identify the definition of an identity matrix, which is a square matrix with ones on the main diagonal and zeros elsewhere.

2. Determine the dimensions for a 2×2 matrix, which consists of 2 rows and 2 columns.

3. Construct the matrix by placing a 1 at position (1,1) and position (2,2) and a 0 at position (1,2) and position (2,1)

Final Answer

(I_2)=([1,0],[0,1])
