3. Coefficient
The numerical part of a term.
4. Degree of a term
The number of variables multiplied to get a term. (Add exponents)

14. Rational Expression
The quotient of 2 polynomials.
15. Sequence
An ordered list of numbers called terms. Each successive number follows the previous according to a uniform rule.
16. Finite Sequence
Has a last term.
17. Infinate Sequence
Never ending use
18. Index
The term number
19. General term
The name given to tn. The rule or formula of the sequence.
20. Arithmatic Sequence
Each term is found by adding the same number (constant) to the previous term.
21. Common difference
The constant that is added to each term to get the next term.
22. Geometric sequence
Each term is found by multiplying the same number(constant) to the previous term.
23. Common ratio
The number that is multiplied to each term to get the next term.
24. Explicit Formulas
The Arithmatic and geometric formulas.
25. Recursion Formula
A different formula to express sequences,arithmatic, geometric, and other. Has 2 parts the first term, and the formula which refers to the previous term t(n-1).
26. Series
The sum of a sequence. Has + signs instead of commas between terms.
27. Sums
The sum of a sequence.
28. Raticals
Irrational numbers (non terminating, non repeating)
29. 3 ways to solve quadratic equations
Factoring, Quadratic Formula, Square root method.
30. Discriminant
Tells the number of solutions or roots.
31. Open circle
Greater than (boundary not included)
32. Closed circle
Less than (boundary included)
33. Union
(or) Combine all possible solutions.
34. Intersections
(and) Only elements common to both sets (overlapping region only).
35. Inequation
An equation with an inequality.
36. Relation
The relationship between 2 variables.
37. Functions
A relation in which each x-value produces only one unique y-value.
38. Domain
Set of all first components (Independant values)
39. Range
Set of all second components( Dependant values)
40. The Winding Function
A mapping which associates a number form the real number line with a point (u,v) on the circumference of the circle. This is called the unit circle.
41. Sinosodial Functions
The sine and cosine functions.
42. Periodic Functions
Self repeating graphs.
43. Amplitude
Positive vertical distance between the aoc and the max.
44. Period
The length of one complete cycle.
45. Axis of the curve
A horizontal line that lies halfway between the max and the min.
46. Cycle of a graph
The smallest repeating unit.
47. Standard position
When the initial arm is at the positive x axis and the terminal arm rotates around the origin forming an angle.
48. Coterminal angle
Angles that have the same initial and terminal arms.
49. Principal angle
The angle between the positive initial arm and the terminal arm. (between 0 and 360 degrees)
50. Related acute angle
The angle between the nearest initial arm and the terminal arm. (between 0 and 90)
