Study Notes

  • Mathematics is the abstract science of number, quantity, and space.
  • Mathematics may be studied in its own right (pure mathematics), or as it is applied to other disciplines such as physics and engineering (applied mathematics).

Core Areas of Mathematics

  • Arithmetic: The study of numbers, especially the properties of the traditional operations between them—addition, subtraction, multiplication, division, exponentiation, and root extraction.
  • Algebra: The study of algebraic structures and the rules for manipulating these structures. Algebra includes solving equations, working with variables and symbols, and understanding relationships between quantities.
  • Geometry: The study of shapes, sizes, positions of figures, and the properties of space. This includes Euclidean geometry (dealing with flat spaces), and non-Euclidean geometries (dealing with curved spaces).
  • Calculus: The study of continuous change, including rates of change, accumulation, and limits. Calculus is the mathematical tool for describing and analyzing motion and continuous processes.
  • Trigonometry: The study of relationships between the angles and sides of triangles. Trigonometry is crucial for fields like surveying, navigation, and engineering.
  • Statistics: The study of the collection, analysis, interpretation, presentation, and organization of data. Statistics is used to make inferences and generalizations from sample data to larger populations.
  • Probability: The measure of the likelihood that an event will occur. Probability theory is used in risk assessment, game theory, and making predictions.
  • Topology: The study of shapes and spaces, focusing on properties that are preserved through continuous deformations, such as stretching, twisting, crumpling, and bending.

Mathematical Concepts

  • Axiom: A statement that is accepted as true without proof. Axioms serve as the starting points for deductive reasoning.
  • Theorem: A statement that has been proven to be true based on axioms and previously established theorems.
  • Lemma: A minor, proven proposition used as a stepping stone to prove a larger theorem.
  • Corollary: A statement that follows directly from a theorem.
  • Proof: A logical argument that demonstrates the truth of a statement.
  • Function: A relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output.
  • Algorithm: A step-by-step procedure or set of rules for solving a problem.

Mathematical Notation and Symbols

  • +: Addition
  • -: Subtraction
  • × or *: Multiplication
  • ÷ or /: Division
  • =: Equals
  • ≠: Not equal to
  • <: Less than
  • >: Greater than
  • ≤: Less than or equal to
  • ≥: Greater than or equal to
  • ∑: Summation
  • ∫: Integration
  • √: Square root
  • Ï€: Pi (approximately 3.14159)
  • i: Imaginary unit (√-1)

  • Computer Science: Mathematics is fundamental to computer science, including algorithm design, data structures, and cryptography.
  • Economics: Mathematics is used in economic modeling, optimization, and statistical analysis.
  • Finance: Mathematics is used in financial modeling, risk management, and pricing derivatives.
  • Biology: Mathematics is used in modeling biological systems, analyzing genetic data, and epidemiology.
  • Cryptography: Number theory and algebra form the basis for modern encryption methods, ensuring secure communication.

Mathematical Problem Solving

  • Understanding the Problem: Read and understand the problem statement, identifying key information and what needs to be found.
  • Devising a Plan: Develop a strategy for solving the problem, which may involve using specific formulas, algorithms, or problem-solving techniques.
