|Complex Numbers and the Distributive Law for Complex Numbers, offering a short way to reach and explain trigonometry, the Pythagorean theorem, trig formulas for dot- and cross-products, the cosine law, and a converse to the Pythagorean theorem. A geometric story describes the complex numbers, or what mathematicians since Gauss in the 1840's have regarded as the complex numbers, providing a confirmation of the law of signs for real numbers. With an applet that illustrates operations with complex numbers.|
