Study Notes
Number Systems
- Natural Numbers: 1, 2, 3, ... (positive integers)
- Whole Numbers: 0, 1, 2, 3, ... (non-negative integers)
- Integers: ..., -3, -2, -1, 0, 1, 2, 3, ... (positive and negative whole numbers)
- Rational Numbers: fractions, e.g. 3/4, 22/7 (can be expressed as a ratio of integers)
- Irrational Numbers: non-repeating, non-terminating decimals, e.g. π, e (cannot be expressed as a ratio of integers)
- Real Numbers: includes rational and irrational numbers
- Complex Numbers: includes real numbers and imaginary numbers (e.g. 3 + 4i)
Algebra
- Variables: letters or symbols that represent unknown values
- Constants: numbers that do not change value
- Expressions: combinations of variables, constants, and mathematical operations
- Equations: statements that express the equality of two expressions
- Inequalities: statements that express the relationship between two expressions (e.g. <, >, ≤, ≥)
Geometry
- Points: locations in space, represented by coordinates (e.g. (x, y))
- Lines: sets of points that extend infinitely in two directions
- Rays: lines that extend infinitely in one direction
- Angles: formed by two rays sharing a common endpoint
- Triangles: polygons with three sides and three angles
- Quadrilaterals: polygons with four sides and four angles
Calculus
- Limits: the behavior of a function as the input approaches a certain value
- Derivatives: measures of how a function changes as its input changes
- Integrals: measures of the accumulation of a function over a given interval
- Differentiation: the process of finding derivatives
- Integration: the process of finding integrals
Statistics
- Descriptive Statistics: summary measures of a dataset (e.g. mean, median, mode)
- Inferential Statistics: using sample data to make inferences about a population
- Probability: the study of chance and randomness
- Hypothesis Testing: the process of testing a hypothesis about a population based on sample data
Number Systems
- Natural numbers are positive integers, starting from 1.
- Whole numbers are non-negative integers, including 0.
- Integers are positive and negative whole numbers, including 0.
- Rational numbers are fractions that can be expressed as a ratio of integers, such as 3/4 or 22/7.
- Irrational numbers are non-repeating, non-terminating decimals, such as π or e, and cannot be expressed as a ratio of integers.
- Real numbers include both rational and irrational numbers.
- Complex numbers include real numbers and imaginary numbers, such as 3 + 4i.
