Lecture

Quadratic Approximation: Example

Description

This lecture discusses finding the best quadratic approximation for the function f(x) = |x| using a polynomial of degree ≤ 2 in the space of continuous functions. It covers the process of Gram-Schmidt, constructing an orthogonal basis, and projecting f onto P₂(R). The lecture also explores the calculation steps involved in determining the quadratic approximation.
