The right triangle definitions of sine and cosine only apply to acute angles, so a more complete definition is needed. The point where the terminal side intersects the unit circle (x, y) is the basis for this definition. Since the radius (and therefore hypotenuse of the right triangle) is 1, the denominators cosine=adjacent/hypotenuse and sine=opposite/hypotenuse are also 1. Thus, the sine definition is y=sine and x=cosine.
What is Faux Leather? Faux leather is one of several names given to artificial or synthetic leather. These names are often used to describe specific end uses of synthetic leather products such as faux leather (sofa, chair and headboard upholstery), leatherette (auto upholstery, clothing), and koskin (consumer goods).
GLAZED FINISH-Similar to an aniline finish except that the leather surface is polished to a high luster by the action of glass on steel rollers under tremendous pressure. GLOVE LEATHER-A term used to describe soft leather used for gloves, which is normally lambskin. The term is also used by some to define soft leather. GRAIN (LEATHER)-The outside of the hide or skin consisting of the pores, wrinkles and other characteristics which constitute the natural texture of the leather.
