  1. 1. (Tier 3) The trigonometric function the ratio of the side opposite side to the given angle over the hypotenuse side of the given angle
  2. 3. (Tier 3) The trigonometric function the ratio of the side adjacent side to the given angle over the hypotenuse side of the given angle
  3. 5. (Tier 2) A diagram showing the relation between variable quantities - typically of two variables - each measured along one of a pair of axes at right angles
  4. 6. (Tier 3) A quantity representing the power to which a fixed number (the base) must be raised to produce a given number
  5. 8. (Tier 3) The branch of mathematics dealing with the relations of the sides and angles of triangles and with the relevant functions of any angles
