Introduction

In linear algebra, a matrix is a rectangular array of numbers, symbols, or expressions, arranged in rows and columns. One of the fundamental operations in matrix algebra is finding the transpose of a matrix. The transpose of a matrix is an essential concept in various fields, including mathematics, physics, engineering, and computer science. In this article, we will explore the concept of the transpose of a matrix, its properties, and how to find it.

What is the Transpose of a Matrix?

The transpose of a matrix is an operator that can be thought of as "swapping" the rows and columns of a matrix. Given a matrix A, its transpose is denoted by A^t or A^T. The transpose of a matrix is obtained by interchanging its rows into columns or columns into rows.

Properties of the Transpose

The transpose of a matrix has several important properties, which are essential in understanding its behavior. Some of the key properties of the transpose are:

Symmetric Property: If A is a symmetric matrix, then A = A^t.
Skew-Symmetric Property: If A is a skew-symmetric matrix, then A = -A^t.
Orthogonal Property: If A is an orthogonal matrix, then A^t A = AA^t = I, where I is the identity matrix.
Inverse Property: If A is an invertible matrix, then (A^t)-1 = (A^-1)t.

Finding the Transpose of a Matrix

To find the transpose of a matrix, we need to interchange its rows into columns or columns into rows. Let's consider an example to illustrate this.

Example

Find the transpose of the matrix A = \begin{pmatrix} 1 & 1 & 3 & 5 \ 5 & -1 & 6 & 2 \end{pmatrix}.

Step 1: Write down the given matrix A.

A = \begin{pmatrix} 1 & 1 & 3 & 5 \ 5 & -1 & 6 & 2 \end{pmatrix}

Step 2: Interchange the rows and columns of the matrix A to obtain its transpose A^t.

A^t = \begin{pmatrix} 1 & 5 \ 1 & -1 \ 3 & 6 \ 5 & 2 \end{pmatrix}

However, the above result is not among the options given in the problem. Let's re-examine the problem and try to find the correct transpose.

Re-examining the Problem

A^t = \begin{pmatrix} 1 & 5 \ 1 & -1 \ 3 & 6 \ 5 & 2 \end{pmatrix}
