Study Notes
Fundamental Concepts
- Mathematics is the study of quantity, structure, space, and change.
- It uses logical reasoning and abstract thought to develop theories and solve problems.
- Key branches include arithmetic, algebra, geometry, calculus, and number theory.
- Fundamental operations include addition, subtraction, multiplication, and division.
Number Systems
- Natural numbers (N): Counting numbers (1, 2, 3, ...).
- Whole numbers (W): Natural numbers plus zero (0, 1, 2, 3, ...).
- Integers (Z): Whole numbers 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. Examples include 1/2, 3/4, -2/5.
- Irrational numbers: Numbers that cannot be expressed as a fraction of two integers. Examples include √2, π.
- Real numbers (R): The set of all rational and irrational numbers.
- Complex numbers (C): Numbers that can be expressed in the form a + bi, where a and b are real numbers and i is the imaginary unit (i² = -1).
Algebra
- Variables: Symbols that represent unknown values.
- Equations: Statements that show the equality of two expressions.
- Inequalities: Statements that show the relationship between two expressions using symbols like <, >, ≤, ≥.
- Polynomials: Expressions consisting of variables and coefficients.
- Factoring: Expressing a polynomial as a product of simpler polynomials.
- Solving equations: Finding the values of variables that satisfy the equation.
Geometry
- Shapes: Two-dimensional figures, including triangles, quadrilaterals, and circles.
- Three-dimensional figures, including cubes, spheres, and cones.
- Properties: Describing characteristics of shapes, like angles, sides, and areas.
- Theorems: Rules about geometrical figures and their relationships.
- Measurement: Calculating lengths, areas, and volumes of figures.
Calculus
- Limits: Describing the behavior of a function as its input approaches a certain value.
- Derivatives: Measuring the instantaneous rate of change of a function.
- Integrals: Finding the area under a curve or the accumulated effect of a function.
- Applications: Used in physics, engineering, economics, and other fields to solve problems related to motion, optimization, and accumulation.
Probability and Statistics
- Probability: The study of the likelihood of events.
- Statistics: The collection, analysis, interpretation, presentation, and organization of data.
- Data: Information gathered through observation or experiment.
- Measures of central tendency: Mean, median, and mode; describe the middle of a dataset.
- Measures of dispersion: Variance and standard deviation, describe the spread of the data.
Logic
- Mathematical proofs: Arguments that use deductive reasoning to establish mathematical truths.
- Axioms and postulates: Starting points for a mathematical system.
- Theorems: Statements derived from axioms and postulates using logical deductions.
- Sets and set theory: A fundamental framework for working with collections of mathematical objects.
Applied Mathematics
- Modeling: Creating mathematical representations of real-world phenomena, like population growth or the spread of disease.
- Simulation: Using mathematical models to predict the behavior of a system under various conditions.
- Optimization: Finding the best possible solution to a problem within some constraints.
- Numerical analysis: Approximating solutions to mathematical problems that cannot be solved analytically.
- Discrete mathematics: Focuses on structures and ideas related to discrete objects (not continuous).
Other Important Concepts
- Functions: Relationships between inputs and outputs.
- Matrices: Rectangular arrays of numbers.
- Graph theory: Exploration of graphs consisting of vertices and edges.
- Number theory: Studies integers and properties.
- Trigonometry: Relationships between angles and sides of triangles.
- Different types of mathematical notations.
