Use the Gram-Schmidt process to construct an orthonormal basis for $\mathbb{R}^4$ starting with the following sets of vectors: (a) $(1,0,1,0)^T,(0,1,0,-1)^T,(1,0,0,1)^T,(1,1,1,1)^T$; (b) $(1,0,0,1)^T,(4,1,0,0)^T,(1,0,2,1)^T,(0,2,0,1)^T$.

Key Concepts

Vector Spaces and Bases

A vector space is a mathematical structure formed by a collection of vectors that can be added together and multiplied by scalars. A basis of a vector space is a set of linearly independent vectors whose linear combinations span the entire space. Understanding bases is crucial because they provide the minimal set of vectors needed to represent any element of the space efficiently.

Gram-Schmidt Process

The Gram-Schmidt process is a method in linear algebra used to convert a set of linearly independent vectors into an orthonormal set that spans the same subspace. It works by sequentially subtracting the projections of each vector onto the vectors already processed, ensuring that each new vector is orthogonal to the previous ones before normalizing it to unit length.

Orthonormal Basis

An orthonormal basis for a vector space is a collection of vectors that are both orthogonal (i.e., their inner product is zero) and normalized (each vector has a unit length). This property simplifies many operations in linear algebra such as solving systems, computing projections, and decomposing vectors since the coefficients can be directly computed using dot products.

Projection

Projection in the context of the Gram-Schmidt process refers to the operation where a vector is expressed in terms of another by computing the component of the vector that lies along the direction of the other vector. This is typically done using the dot product and is essential for subtracting out parts of a vector that are in the direction of an existing orthogonal basis vector.
