Study Notes
Key Areas of Mathematics
1. Algebra
- Involves symbols and letters to represent numbers and quantities in formulas and equations.
- Key concepts include:
- Variables: Symbols that represent unknown values.
- Expressions: Combinations of numbers, variables, and operations (e.g., 2x + 3).
- Equations: Mathematical statements that show the equality of two expressions (e.g., 2x + 3 = 7).
- Functions: A relation that assigns exactly one output for each input (e.g., f(x) = x^2).
2. Geometry
- Study of shapes, sizes, and properties of space.
- Key concepts include:
- Points, lines, angles, and planes.
- Shapes: Triangles, quadrilaterals, circles, and polygons.
- Theorems: Pythagorean theorem, properties of similar and congruent shapes.
- Area and volume calculations for various shapes.
3. Trigonometry
- Focuses on the relationships between the angles and sides of triangles.
- Key concepts include:
- Sine, cosine, and tangent functions.
- Unit circle and radians.
- Trigonometric identities (e.g., sin²x + cos²x = 1).
- Applications in real-world scenarios (e.g., waves, oscillations).
4. Calculus
- The study of change and motion, dealing with derivatives and integrals.
- Key concepts include:
- Limits: The value that a function approaches as the input approaches a point.
- Derivatives: Measures how a function changes as its input changes (e.g., velocity).
- Integrals: Represents the accumulation of quantities (e.g., area under curves).
- Fundamental Theorem of Calculus: Links differentiation and integration.
5. Statistics
- The science of collecting, analyzing, interpreting, and presenting data.
- Key concepts include:
- Descriptive statistics: Mean, median, mode, and standard deviation.
- Probability: The measure of the likelihood of an event occurring.
- Distributions: Normal distribution, binomial distribution.
- Inferential statistics: Drawing conclusions from data samples (e.g., hypothesis testing).
6. Number Theory
- Study of integers and their properties.
- Key concepts include:
- Prime numbers: Numbers greater than 1 that have no positive divisors other than 1 and themselves.
- Divisibility rules and greatest common divisors (GCD).
- Modular arithmetic: A system of arithmetic for integers, where numbers wrap around upon reaching a certain value (mod).
Mathematical Processes
- Problem-solving: The methodical approach to finding solutions to mathematical questions.
- Logical reasoning: Drawing conclusions based on given facts and principles.
- Mathematical modeling: Using mathematics to represent real-world scenarios for analysis and predictions.
