trigonometric functions
... A triangle is a right triangle if one of its angles is a right angle. If is any acute angle, we may consider a right triangle having as one of its angles, as in Figure 1, where the symbol specifies the 90° angle. ...

Notes on Axiomatic Geometry
... • Axiom I − 1. There exist at least two points. • Axiom I − 2. Any two points lie on exactly one line. This is our version of Euclid’s Postulate 1 ([E] Book 1). The word “exactly” means there are actually two statements, called “existence” and “uniqueness”: I − 2 − i. If P is a point, and Q is a p ...
