Module 7: Inner Product Spaces

Explore the geometry of vector spaces through dot products, orthogonality, projections, and the Gram-Schmidt process, culminating in least-squares applications.

Module Lessons

1

Dot Product, Length, and Orthogonality

Define the dot product and its properties, compute vector lengths and distances, and understand orthogonal sets.

2

Orthogonal Projections

Project vectors onto lines and subspaces, and decompose vectors using the orthogonal decomposition theorem.

3

The Gram-Schmidt Process

Convert any basis into an orthogonal or orthonormal basis using the Gram-Schmidt algorithm.

4

Least Squares Problems

Solve overdetermined systems using the normal equations and apply least squares to data fitting.
