# English translations

Because the primary aim of this website is to share notes/books I have written for the Danish stx, most of the material is in Danish.

However, for the past few years I have taught a mathematics class in English, and I have, therefore, translated a few of the books into English (corresponding to the Danish B-level in mathematics).

# Basics

# Basic Course Math

Linear functions, piecewise linear functions, and linear regression.
# Arithmetic

Mathematical operations, algebra, equations.
# A/B-level

# Plane Geometry

Plane geometry based on vectors.
# Functions

Mathematical functions in general; different types of functions.
# Interest and annuities

Simple interest, index numbers, savings and loans.
# Differential Calculus

Derivatives, tangents, monotonicity, optimisation, and rate of change.
