# Algebra & trigonometry

The Chinese independently developed very large and negative numbers, decimals, a place value.We assume the student is relatively new to algebra and do algebra step by step.The 3rd-century astronomers first noted that the lengths of the sides of a right-angle triangle and the angles between those sides have fixed relationships: that is, if at least the length of one side and the value of one angle is known, then all other angles and lengths can be determined algorithmically.

These ratios are given by the following trigonometric functions of the known angle A, where a, b and c refer to the lengths of the sides in the accompanying figure.Chapter 0 Algebra and Trigonometry Review 0.1 Elementary Geometry Formulas 0.2 Algebra of Fractions 0.3 Algebra of Exponents 0.4 Algebra of Polynomials.
