# Theory

Goal:
Understand the definition of xr, and the concepts fixed point, fixed point iteration, and contraction mapping. Understand the the idea of coupled systems of equations.
Understand elementary vector algebra, including scaling, addition, scalar multiplication and projection of vectors.
