Are you grappling with your matrix algebra assignment? Fear not, as we delve into one of the toughest topics in this domain, armed with clarity and a step-by-step approach. Matrix algebra is a fundamental concept in mathematics and finds applications across various fields, including computer science, physics, and engineering. Today, we'll unravel the intricacies of a particularly challenging question and guide you through the process of solving it with ease.

Understanding the Question: Let's dive straight into the question at hand:

"Consider a square matrix A. Prove that if A is invertible, then the transpose of A is also invertible."

At first glance, this question might seem daunting, but fret not! We'll break it down into digestible chunks and tackle each part systematically.

Step-by-Step Guide:

  1. Understanding Invertibility: Before we delve into the proof, let's ensure we understand the concept of invertibility. A square matrix is said to be invertible if there exists another matrix, known as its inverse, such that when the matrix and its inverse are multiplied, the result is the identity matrix.

  2. Setting the Stage: We start by assuming that matrix A is invertible. This means there exists another matrix, let's call it B, such that when A and B are multiplied together, we get the identity matrix.

  3. Proving Transpose Invertibility: Now, we aim to prove that the transpose of A, denoted as A^T, is also invertible. To do this, we need to show that there exists another matrix, say C, such that when A^T and C are multiplied, we obtain the identity matrix.

  4. Transpose Properties: Recall that the transpose of a matrix reflects it over its main diagonal. Thus, if A is of dimension m x n, then A^T will be of dimension n x m. Keeping this in mind, let's proceed with our proof.

  5. Utilizing Properties of Inverses: Since A is invertible, we know that A * B = I, where I is the identity matrix. Now, let's consider the product of A^T and a hypothetical matrix D. If A^T * D equals the identity matrix, then we've proven the invertibility of A^T.

  6. Connecting the Dots: To establish this, we leverage the properties of transpose. It can be shown that (A * B)^T = B^T * A^T. Hence, if A * B = I, then (A * B)^T = I^T, which simplifies to B^T * A^T = I.

  7. Concluding the Proof: Therefore, we have shown that if A is invertible, then A^T is also invertible, as there exists a matrix (B^T) such that A^T * B^T = I.
