Study Notes
Branches of Mathematics
- Arithmetic: Deals with basic operations like addition, subtraction, multiplication, and division of numbers.
- Algebra: Uses symbols (variables) to represent numbers and expressions to solve equations and relationships.
- Geometry: Focuses on shapes, sizes, and properties of space. Includes topics like lines, angles, triangles, circles, and 3D shapes.
- Trigonometry: Explores the relationships between angles and sides of triangles. Crucial in physics and engineering.
- Calculus: Deals with continuous change, including differentiation (finding rates of change) and integration (calculating areas and volumes).
- Number theory: Studies the properties of numbers, such as prime numbers, divisibility, and integer sequences.
- Statistics: Collects, analyzes, and interprets numerical data. Involves measures of central tendency (mean, median, mode), variance, probability, and distributions like normal distribution.
- Discrete mathematics: Focuses on countable objects and finite structures, including graph theory, combinatorics, and logic.
- Linear algebra: Studies linear equations, linear transformations, and vector spaces.
Mathematical Concepts
- Sets: Collections of objects. Key concepts include union, intersection, and complements.
- Functions: Relationships between inputs and outputs. Includes domain, range, and various types of functions (linear, quadratic, exponential, etc.).
- Logic: Deals with reasoning and argumentation using statements and connectives (and, or, not).
- Proof: Demonstrating the truth of a mathematical statement using established axioms and rules of inference.
Mathematical Systems
- Real numbers: The set of all numbers that can be represented on a number line. Includes rational and irrational numbers.
- Complex numbers: Extend the real number system to include the square root of negative one (i).
- Vectors: Quantities that have both magnitude and direction. Used in physics and engineering to represent forces, velocities, and other physical quantities.
- Matrices: Rectangular arrays of numbers that can be used to represent and solve systems of linear equations.
Problem-Solving Strategies
- Understanding the problem: Identifying the given information and the desired outcome.
- Devising a plan: Formulating a strategy to solve the problem (e.g., using a formula, drawing a diagram, working backwards).
- Carrying out the plan: Implementing the chosen strategy and performing the necessary calculations.
- Looking back: Checking the solution for accuracy and identifying potential errors. Interpreting the results in the context of the problem.
Tools and Representations
- Equations: Statements of equality between expressions.
- Inequalities: Statements of relationships between expressions that are not equal (e.g., greater than, less than).
- Graphs: Visual representations of data and relationships between variables. Types include Cartesian graphs, bar graphs, pie charts, etc.
- Diagrams: Visual aids that can help visualize geometric shapes and concepts.
Applications of Mathematics
- Computer science: Used in algorithms, data structures, and program design, particularly discrete mathematics.
- Engineering: Essential for designing structures, calculating forces, and modeling systems.
- Physics: Used to describe motion, forces, energy, and other physical phenomena, often involving calculus.
- Finance: Used in investment analysis, risk management, and budgeting.
- Statistics: Used in data analysis across many fields for making sense of large amounts of information, like polling and medical research.
- Biology: Needed for modelling population growth, genetics, and evolution.
Mathematical Notation
- Symbols for operations (e.g., +, -, ×, ÷).
- Variables (e.g., x, y, z).
- Greek letters (e.g., π, Σ, μ).
- Mathematical functions (e.g., sin, cos, log).
- Set notation (e.g., ∈, ∪, ∩).
