Key Areas of Mathematics

• Arithmetic

  • Fundamental operations: Addition, Subtraction, Multiplication, Division form the basis of mathematics.
  • Properties include Commutative (order doesn't matter), Associative (grouping doesn't matter), and Distributive (a(b+c) = ab + ac).
  • Order of operations is critical and is remembered by PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction) or BODMAS.

• Algebra

  • Involves using variables (letters) in place of numbers and working with constants.
  • Key concepts include expressions (mathematical phrases) and equations (statements that two expressions are equal).
  • Linear equations have the form y = mx + b, while inequalities express a relationship where one value is greater or less than another.
  • Quadratic equations can be solved by factoring or applying the quadratic formula: x = [-b ± sqrt(b² - 4ac)] / 2a.
  • Functions map inputs to outputs and can be linear, quadratic, or exponential in nature.

• Geometry

  • Basic shapes include triangles, circles, and quadrilaterals, each with specific properties.
  • Measurement properties involve understanding angles, calculating perimeter, area, and volume.
  • Important theorems include the Pythagorean theorem (a² + b² = c² for right triangles) and properties related to parallel lines.
  • Coordinate Geometry involves plotting points, calculating slopes, and using the distance formula between two points.

• Trigonometry

  • Trigonometric ratios such as Sine (opposite over hypotenuse), Cosine (adjacent over hypotenuse), and Tangent (opposite over adjacent) are fundamental.
  • The unit circle provides a way to visualize angles in both degrees and radians.
  • Key identities include the Pythagorean identity (sin²θ + cos²θ = 1) and angle sum/difference formulas which help in simplifying expressions.
  • Applications include solving triangles through various methods and understanding periodic functions.

• Calculus

  • Limits describe the behavior of functions as they approach specific points.
  • Derivatives quantify how a function changes and have rules like product, quotient, and chain for differentiation.
  • Integrals can be definite (calculate the area under the curve) or indefinite (find the antiderivative), guided by the Fundamental Theorem of Calculus.
  • Applications encompass finding areas under curves and calculating volumes of solids of revolution.

• Statistics and Probability

  • Descriptive Statistics summarize data using mean (average), median (middle value), mode (most frequent), variance, and standard deviation.
  • Probability involves calculating chances and includes rules for addition and multiplication, as well as conditional probabilities.
  • Statistical distributions like normal and binomial help model data variation.
  • Inferential statistics focus on making predictions from sample data, including hypothesis testing and confidence intervals.

• Discrete Mathematics

  • Sets are collections of distinct objects with operations like union (combining sets) and intersection (common members).
  • Combinatorics concerns counting arrangements (permutations) and selections (combinations).
  • Graph theory studies graphs composed of vertices and edges, including paths and cycles.
  • Logic involves propositions, truth tables, and logical operations crucial for reasoning.

• Number Theory

  • Prime numbers are defined as being divisible only by 1 and themselves; important properties include the distribution of primes and Euclid’s theorem.
  • Rules of divisibility aid in identifying relationships between numbers.
  • The Greatest Common Divisor (GCD) and Least Common Multiple (LCM) are foundational in understanding number relationships.
  • Modular arithmetic is useful in various applications, including cryptography.
