Study Notes
Branches of Mathematics
- Arithmetic: Study of numbers and basic operations (addition, subtraction, multiplication, division).
- Algebra: Focus on symbols and rules for manipulating those symbols (equations, polynomials).
- Geometry: Study of shapes, sizes, and properties of space (points, lines, angles, surfaces).
- Trigonometry: Study of relationships between angles and sides of triangles.
- Calculus: Examination of change through derivatives and integrals; focuses on limits, functions.
- Statistics: Collection, analysis, interpretation, and presentation of data.
- Probability: Study of uncertainty and chance; quantifies the likelihood of events.
Fundamental Concepts
-
Number Systems:
- Natural Numbers: Counting numbers (1, 2, 3,...).
- Whole Numbers: Natural numbers including zero (0, 1, 2, ...).
- Integers: Whole numbers and their negatives (..., -2, -1, 0, 1, 2,...).
- Rational Numbers: Numbers that can be expressed as a fraction of two integers.
- Irrational Numbers: Numbers that cannot be expressed as a simple fraction (π, √2).
- Real Numbers: All rational and irrational numbers.
Key Mathematical Operations
- Addition (+): Combining quantities.
- Subtraction (−): Finding the difference between quantities.
- Multiplication (×): Scaling one quantity by another.
- Division (÷): Splitting a quantity into equal parts.
Algebraic Principles
- Variables: Symbols that represent numbers (e.g., x, y).
- Expressions: Combinations of numbers and variables (e.g., 3x + 4).
- Equations: Mathematical statements asserting equality (e.g., 2x + 3 = 7).
- Functions: Relationships where each input has a single output (e.g., f(x) = 2x + 1).
Geometry Essentials
-
Types of Angles:
- Acute: < 90°
- Right: = 90°
- Obtuse: > 90° but < 180°
- Straight: = 180°
- Triangles: Classified by angles (acute, obtuse, right) and sides (scalene, isosceles, equilateral).
-
Area and Perimeter:
- Rectangle: Area = length × width; Perimeter = 2(length + width).
- Circle: Area = πr^2; Circumference = 2πr.
Calculus Concepts
- Limits: Value that a function approaches as the input approaches a point.
- Derivatives: Measures the rate of change of a function.
- Integrals: Represents accumulation, area under a curve.
Statistics Overview
- Descriptive Statistics: Summarizes data (mean, median, mode).
- Inferential Statistics: Makes predictions or inferences based on a sample.
- Distributions: Describes how values are spread (normal distribution, binomial distribution).
Probability Terms
- Experiment: A procedure that yields one of a possible set of outcomes.
- Event: A specific outcome or set of outcomes from an experiment.
- Sample Space: The set of all possible outcomes.
- Probability: Measure of the likelihood of an event occurring, expressed as a number between 0 and 1.
Math Problem-Solving Techniques
- Understand the Problem: Read carefully and interpret what is being asked.
- Devise a Plan: Determine strategies for solving the problem (drawing diagrams, making lists).
- Carry Out the Plan: Implement the strategy chosen.
- Review/Check: Evaluate the solution to ensure accuracy and completeness.
