An inner product defined on the vector space $P_{2}$ of all polynomials of degree less than or equal to 2 , is given by $$ (p, q)=\int_{-1}^{1} p(x) q(x) d x $$ Use the Gram-Schmidt orthogonalization process to transform the given basis $B$ for $P_{2}$ into an orthogonal basis $B^{\prime}$. $$ B=\left\{x^{2}-x, x^{2}+1,1-x^{2}\right\} $$

Key Concepts

Gram-Schmidt Process

The Gram-Schmidt process is a systematic method for converting a set of linearly independent vectors into an orthogonal (or orthonormal) set while preserving the span of the original vectors. It achieves this by sequentially subtracting out the projections of each vector onto the previously processed orthogonal vectors, ensuring that the result at each step is orthogonal to those that came before.

Orthogonal Basis

An orthogonal basis of a vector space is a set of basis vectors that are mutually perpendicular with respect to a defined inner product. This property simplifies many computations in linear algebra, including projections of vectors, representations of vectors in the space, and solving systems of equations.

Inner Product

An inner product is a function that accepts two vectors and returns a scalar, providing a notion of angle and length in a vector space. It satisfies properties such as linearity, symmetry (or conjugate symmetry in complex spaces), and positive-definiteness, and is fundamental in defining concepts like orthogonality, projection, and norm within the space.

Vector Space

A vector space is a collection of objects called vectors that can be added together and multiplied by scalars while satisfying certain axioms. It provides the foundational structure where operations such as linear combinations, spanning sets, and basis transformations are defined and studied.
