Study Notes

Fundamental Concepts

  • Mathematics is a formal system of logical reasoning used to quantify, analyze, and model phenomena spanning diverse fields like physics, engineering, and computer science.
  • Core concepts include numbers, operations, geometry, algebra, calculus, and probability.
  • Mathematics evolves through abstractions, axioms, and theorems, forming a hierarchical structure built upon foundational principles.
  • Different branches of mathematics include arithmetic, algebra, geometry, calculus, and discrete mathematics, each with its own set of tools and applications.

Number Systems

  • Natural numbers (ℕ): Positive integers (1, 2, 3,…) used for counting.
  • Integers (ℤ): Include natural numbers, zero, and their negative counterparts (-3, -2, -1, 0, 1, 2, 3,…)
  • Rational numbers (ℚ): Numbers that can be expressed as a fraction p/q, where p and q are integers and q ≠ 0 (e.g., 1/2, -3/4, 5).
  • Irrational numbers: Numbers that cannot be expressed as a fraction of two integers (e.g., √2, π).
  • Real numbers (ℝ): Include all rational and irrational numbers.
  • Complex numbers (ℂ): Numbers of the form a + bi, where a and b are real numbers, and i is the imaginary unit (i² = -1).

Arithmetic Operations

  • Addition (+): Combining numbers to form a sum.
  • Subtraction (-): Finding the difference between two numbers.
  • Multiplication (× or ⋅): Repeated addition of a number.
  • Division (/ or ÷): Finding how many times one number contains another.
  • Exponents: Repeated multiplication of a number by itself (e.g., 2³ = 2 × 2 × 2 = 8).

Algebra

  • Variables: Symbols (usually letters) representing unknown quantities.
  • Equations: Statements that assert the equality of two expressions.
  • Solving equations: Finding the values of variables that make the equation true.
  • Inequalities: Relations that compare values using symbols like <, >, ≤, ≥.

Geometry

  • Shapes: Two-dimensional (2D) figures like triangles, squares, circles, polygons and three-dimensional (3D) figures like cubes, spheres, and cones.
  • Angles: Measurements of the space between two intersecting lines or rays.
  • Lines: Straight paths that extend infinitely in both directions.
  • Planes: Flat surfaces that extend infinitely in all directions.

Calculus

  • Derivatives: Rate of change of a function.
  • Integrals: Accumulation of a function over an interval.
  • Differentiation: Process of finding the derivative.
  • Integration: Calculating the integral.
  • Applications: Modeling motion, optimization, and solving various scientific and engineering problems.

Probability and Statistics

  • Probability: Measure of the likelihood of an event occurring.
  • Statistics: Collection, organization, analysis, interpretation, and presentation of data.
  • Data analysis: Studying patterns, trends, and relationships within datasets.
  • Descriptive statistics: Summarizing and describing data using measures like mean, median, and standard deviation.

Logic and Proof

  • Formal systems (axioms, theorems, and proofs) within mathematics allow for the deduction of new truths based on established principles and definitions.
  • Deductive reasoning: Drawing conclusions from general principles.
  • Mathematical proofs: Rigorous arguments demonstrating the validity of mathematical statements.
  • Indeterminate vs. determinate conclusions.

Applications of Mathematics

  • Mathematics finds applications across a vast range of disciplines.
  • Including: Physics, engineering, computer science, economics, medicine, and social sciences.
  • Mathematical modeling is widely used to create simulations and predict outcomes in diverse fields.

Discrete Mathematics

  • Deals with discrete elements and structures, not continuous ones like calculus.
  • Includes topics like graph theory, combinatorics, logic, and number theory.
  • Often used in computer science for algorithm design and analysis.
