Study Notes
Fundamental Concepts
- Mathematics is a field of study focused on abstract concepts like quantity, structure, space, and change. It uses symbols and logical reasoning to solve problems and understand patterns.
- Key branches include arithmetic, algebra, geometry, calculus, and number theory, each with its own set of principles and applications.
- Mathematics is essential for various scientific disciplines and technological advancements.
Number Systems
- Natural numbers (counting numbers): 1, 2, 3,...
- Whole numbers: 0, 1, 2, 3,...
- Integers:..., -3, -2, -1, 0, 1, 2, 3,...
- Rational numbers: numbers that can be expressed as a fraction p/q, where p and q are integers and q ≠ 0. Examples: 1/2, 3/4, -2/5
- Irrational numbers: numbers that cannot be expressed as a fraction of two integers. Examples: π (pi), √2
- Real numbers: the set of all rational and irrational numbers
- Complex numbers: 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).
Arithmetic Operations
- Addition (+): combining quantities
- Subtraction (-): finding the difference between two quantities
- Multiplication (× or *): repeated addition
- Division (/): finding how many times one quantity is contained within another
- Order of operations (PEMDAS/BODMAS): Parentheses/Brackets, Exponents/Orders, Multiplication and Division (left to right), Addition and Subtraction (left to right)
Algebra
- Variables: symbols that represent unknown quantities.
- Equations: mathematical statements that show the equality of two expressions. Example: 2x + 3 = 7
- Inequalities: mathematical statements that show an inequality between two expressions. Example: x > 5
- Solving equations/inequalities: finding the value(s) of the variable(s) that satisfy the equation or inequality.
- Polynomials: expressions involving variables and constants, combined through addition, subtraction, and multiplication. Example: 3x² + 2x - 1
- Factoring: rewriting an expression as a product of simpler expressions.
Geometry
- Shapes and figures: points, lines, angles, triangles, circles, polygons, etc.
- Measurement: length, area, volume, angles
- Properties of shapes: relationships between sides and angles
- Transformations: translations, rotations, reflections, dilations
- Coordinate geometry: using coordinates to represent points and shapes in a plane and space
Calculus
- Limits: behavior of a function as its input approaches a certain value
- Derivatives: rate of change of a function
- Integrals: finding the area under a curve
- Applications: motion, optimization, modeling real-world phenomena
Logic and Proof
- Deductive reasoning: deriving conclusions from premises using logical rules
- Inductive reasoning: forming generalizations based on observations
- Mathematical proofs: demonstrating the truth of a statement through logical argumentation
- Axioms/Postulates: fundamental assumptions in a mathematical system
- Theorems: statements that can be proven based on axioms and previously proven theorems
Set Theory
- Sets: collections of objects
- Operations on sets: union, intersection, complement
- Venn diagrams: visual representations of sets and their relationships
Discrete Mathematics
- Counting techniques: combinations and permutations
- Graphs and networks
- Logic and proofs in discrete systems
- Applications in computer science and related fields
Probability and Statistics
- Probability: the likelihood of an event occurring
- Statistical measures: mean, median, mode, standard deviation
- Data analysis and interpretation
