Study Notes
Fundamental Concepts
- Mathematics is the study of quantity, structure, space, and change.
- It involves the use of logic and abstract reasoning to understand and solve problems.
- Different branches of mathematics exist, each focusing on specific aspects of these concepts.
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 is not zero.
- Irrational numbers: numbers that cannot be expressed as a fraction of two integers. Examples include π (pi) and the square root of 2.
- Real numbers: include both rational and irrational numbers.
- Imaginary numbers: numbers containing the imaginary unit "i" where i2 = -1.
- 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.
Arithmetic Operations
- Addition (+): combining quantities.
- Subtraction (-): finding the difference between quantities.
- Multiplication (× or ⋅): repeated addition.
- Division (÷ or /): separating a quantity into equal parts.
- Exponentiation (^): repeated multiplication.
- Properties of operations (commutative, associative, distributive).
Algebra
- Variables and expressions: representing unknown quantities with symbols.
- Equations and inequalities: statements of equality or inequality.
- Solving equations and inequalities: finding the values of the variables that satisfy the equation or inequality.
- Polynomials: expressions involving variables and exponents.
- Factoring: rewriting an expression as a product of simpler expressions.
Geometry
- Shapes and figures: points, lines, angles, polygons, circles, etc.
- Measurements: lengths, areas, volumes, angles.
- Geometric figures properties: identifying and classifying shapes, exploring relationships between their components.
Trigonometry
- Study of triangles and relationships between their sides and angles.
- Trigonometric functions (sine, cosine, tangent, etc.).
- Applications in various fields like physics and engineering.
Calculus
- Differential calculus: deals with rates of change and slopes of curves.
- Integral calculus: deals with accumulation and areas under curves.
- Applications: optimization problems, motion analysis, and finding areas and volumes.
Discrete Mathematics
- Study of structures and quantities that are discrete rather than continuous, like graphs, trees, and sets.
- Concepts like combinations, permutations, graph theory, and logic.
Statistics and Probability
- Collection, organization, analysis, and interpretation of numerical data.
- Probability: quantifying the likelihood of events happening.
- Statistical measures: mean, median, mode, variance, standard deviation.
