Welcome to the world of matrix algebra, where students often find themselves navigating through complex mathematical terrain. In this blog, we aim to shed light on a challenging matrix algebra assignment question and provide you with a comprehensive step-by-step guide to tackle it successfully. Whether you're a university student seeking assistance or someone keen on mastering matrix algebra concepts, this blog is your go-to resource.

Understanding the Challenge:

Let's delve into a tricky question that often leaves students scratching their heads:

Question:

Consider a square matrix A of order n with distinct eigenvalues. Prove that A is diagonalizable.

Conceptual Overview:

Before we jump into the solution, let's break down the core concepts embedded in the question.

1. Square Matrix (A): A matrix where the number of rows is equal to the number of columns.

2. Eigenvalues: These are special numbers associated with a square matrix, representing the scalar values for which the matrix equation Av = λv holds true, where A is the matrix, v is the eigenvector, and λ is the eigenvalue.

3. Diagonalizable Matrix: A square matrix is said to be diagonalizable if it is similar to a diagonal matrix, meaning it can be transformed into a simpler, diagonal form.

Step-by-Step Guide: Now, let's unravel the mystery of proving that a square matrix A with distinct eigenvalues is diagonalizable.

Step 1: Understand Eigenvalues and Eigenvectors

Begin by understanding the fundamental concept of eigenvalues and eigenvectors. Recall that for distinct eigenvalues, the corresponding eigenvectors are linearly independent.

Step 2: Form the Diagonal Matrix

Since A has distinct eigenvalues, construct a diagonal matrix D using these eigenvalues. Arrange them on the diagonal of D.

Step 3: Find Inverse Matrix P

Determine the matrix P by using the linearly independent eigenvectors corresponding to the distinct eigenvalues. Arrange these eigenvectors as columns of P.

Step 4: Verify Diagonalizability

Show that A is similar to the diagonal matrix D through the relation P^(-1)AP = D. This verifies the diagonalizability of A.
