What Every Mathematics Major Should Know
- Linear algebra including:
- axiomatic characterization of determinant.

of an orthogonal matrix with a positive-definite

and connectedness. Generalization of the extreme and
intermediate value theorems. Metric spaces: equivalence
of compactness with "complete and totally bounded".

theory in characteristic zero.
