Proposition. Let f : R R. Then (regardless of whether f is a Borel function) the set

D = cfw_x R : f is discontinuous at x,
is a Borel set.
Proof. Recall that f is continuous

Vector Spaces
As usual, a collection of objects will be called a set. A member of the
collection is also called an element of the set. It is useful in practice to
use short symbols to denote

SUBSPACES
After many attempts at formalizing space and spatial relationships, the concept of a vector
space emerged as the useful framework for geometrical computations. We use it
