- 3. A number that, when multiplied by itself, produces the given number.
- 4. A curve that can be obtained when cutting a right circular cone by a plane parallel to one of the elements of the cone.
- 5. A statement that the values of two mathematical expressions are equal.
- 7. A way of simplifying/solving a quadratic equation by adding an expression to both sides to make one part of the equation a perfect square.
- 10. A number or algebraic expression by which another is exactly divisible.
- 11. Expressible, or containing quantities that are expressible, as a ratio of whole numbers. When expressed as a decimal, a rational number has a finite or recurring expansion.
- 12. The trigonometric function that is equal to the ratio of the side opposite a given angle (in a right triangle) to the hypotenuse.
- 13. The trigonometric function that is equal to the ratio of the side adjacent to an acute angle (in a right-angled triangle) to the hypotenuse.
- 14. The trigonometric function that is equal to the ratio of the sides (other than the hypotenuse) opposite and adjacent to an angle in a right triangle.
