( \newcommand{\kernel}{\mathrm{null}\,}\)
- 7.1: A - Complex Numbers
- This page reviews the arithmetic of complex numbers, introducing the imaginary unit i and defining complex numbers as a+bi. It covers operations such as addition, multiplication, and complex conjugation. The Fundamental Theorem of Algebra is discussed, stating that every polynomial of degree n has n complex roots, including complex conjugates. Examples are provided to demonstrate how to find these complex roots.
- 7.2: B - Notation
- This page includes a table detailing mathematical symbols, their meanings, and first appearances in a book. It covers symbols for numbers, matrices, transformations, vector spaces, and complex numbers, providing readers with a quick reference to understand the notation used in various mathematical concepts.
