4. the trigonometric function that is equal to the ratio of the side adjacent to an acute angle to the hypotenuse.(formula. adjacent / hypotenuse).
5. a straight line or plane that touches a curve or curved surface at a point, but if extended does not cross it at that point. (formula. opposite / adjacent).
6. the ratio of each term of a geometric progression to the term preceding it. (ex. 1, 2, 4, 8, 16, 32, 64).
7. Opposite or reverse (ex. x - 1, = 1/x)
12. the relationship in quantity, amount, or size between two or more things (ex. 1:5)
