Across
- 2. A trigonometric function that relates the ratio of the opposite side to the adjacent side in a right triangle.
- 6. A trigonometric function that relates the ratio of the opposite side to the adjacent side in a right triangle.
- 8. A function that relates an angle of a triangle to the ratio of two sides of the triangle.
- 10. The reciprocal of sine
- 11. A trigonometric function that relates the ratio of the opposite side to the hypotenuse in a right triangle

Down
- 1. A fundamental theorem in geometry stating that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
- 3. The side of a triangle that is across from a given angle.
- 4. The four regions of the coordinate plane, often used to define the sign of trigonometric functions.
- 5. The reciprocal of cosine
- 7. A figure formed by two rays or lines that share a common endpoint.
- 9. A mathematical relationship where each input has exactly one output.
- 12. The reciprocal of cosine
- 14. The side of a triangle that is next to a given angle and not the hypotenuse.
- 15. The maximum displacement of a periodic function from its equilibrium position.
- 16. The distance or interval after which a periodic function repeats its values.
