1. Angle in Standard Position
An angle whose initial ray is on the positive side of the x-axis and whose vertex is at the origin.
2. Reference Angle
The positive acute angle formed by the terminal ray of an AISP and the x-axis.
The length of the intercepted arc divided by the radius (when the angle has its vertex a the center of a circle).
4. Unit Circle
A circle whose radius is 1.
5. Co-terminal Angles
2 AISP that have the same terminal ray.
An AISP that has its terminal ray on the x or y axis.
7. Sine
the function that pairs the AISP with the y coordinate of point P*
8. Cosine
the function that pairs the AISP with the x coordinate of point P
9. Amplitude
Half the difference of y-max and y-min
10. Frequency
The number of cycles drawn from 0 to 2pi.
11. Period
The length of the interval necessary to see one full cycle.
12. Tangent
The function that pairs the AISP with the y coordinate of point P divided by the x coordinate of point P.
13. Secant
The function that pairs the AISP with the reciprocal of the x coordinate of point P.
14. Cosecant
The function that pairs the AISP with the reciprocal of the y coordinate of point P.
15. Cotangent
The function that pairs the AISP with the x coordinate of point P divided by the y coordinate of point P.
16. Inverse of the Sine
pairs the y coordinate of point P with the AISP
17. Inverse of the Cosine
pairs the x coordinate of point P with the AISP.
18. Inverse of the Tangent
pairs the y coordinate of point P divided by the x coordinate of point P with the AISP
19. Inverse of the Cotangent
pairs the x coordinate of point P divided by the y coordinate of point P with the AISP
20. Inverse of the Secant
pairs the reciprocal of the x coordinate of point P with the AISP
21. Inverse of the Cosecant
pairs the reciprocal of the y coordinate of point P with the AISP
22. Point P
the point on the unit Circle where the terminal ray of an AISP intersects it
