Across
- 1. A rule or relationship that assigns exactly one output value for each input value. Used often in Trig.
- 8. A trigonometric function that is the ratio of the length of the side adjacent to an angle to the length of the hypotenuse in a right triangle.
- 10. The side of a right triangle that is next to a given angle (not the hypotenuse).
- 12. An angle of this type is formed by a horizontal line and a line of sight above that line.
- 13. A trigonometric function that is the ratio of the length of the side opposite an angle to the length of the side adjacent to the angle in a right triangle.
- 14. The property of a function (like sine, cosine, and tangent) where its values repeat at regular intervals.
- 15. Trigonometric Functions that "undo" trigonometric functions, such as arccosine, arcsine, and arctangent.
- 16. The branch of mathematics that deals with the relationships between the sides and angles of triangles.
- 18. The side of a right triangle that is across from a given angle.
- 20. A trigonometric function that is the ratio of the length of the side opposite an angle to the length of the hypotenuse in a right triangle.
Down
- 2. A trigonometric function that is the reciprocal of the sine function.
- 3. An angle of this type formed by a horizontal line and a line of sight below that line.
- 4. The side of a right triangle opposite the right angle.
- 5. Another unit of angle measurement, where a full circle is 360 degrees.
- 6. The reciprocal of the tangent function
- 7. A figure formed by two rays or line segments that share a common endpoint.
- 9. The theorem stating that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
- 11. A type of triangle with one right angle (90 degrees).
- 17. A unit of angle measurement involving pi
- 19. A trigonometric function that is the reciprocal of the cosine function.
