Trig - francisco

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
13. A unit of angle measurement, where one radian is the angle subtended at the center of a circle by an arc equal in length to the radius of the circle.
17. An angle that measures 90 degrees.
18. The branch of mathematics that deals with the relationships between angles and the sides of triangles
19. A trigonometric function that relates the ratio of the adjacent side to the hypotenuse in a right triangle.

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.
