Study Notes
Fundamental Concepts
- Mathematics is a system for rigorously describing patterns and relationships.
- It uses symbolic language to represent abstract ideas.
- It explores various types of numbers, sets, and operations.
- It reveals underlying structures in diverse areas.
- Key branches include algebra, geometry, calculus, and number theory.
Number Systems
- Natural numbers ($\mathbb{N}$): Counting numbers (1, 2, 3, ...).
- Whole numbers ($\mathbb{W}$): Natural numbers plus zero (0, 1, 2, 3, ...).
- Integers ($\mathbb{Z}$): Whole numbers and their negatives (... -3, -2, -1, 0, 1, 2, 3, ...).
- Rational numbers ($\mathbb{Q}$): Numbers that can be expressed as a fraction p/q, where p and q are integers, and q≠0. Include terminating and repeating decimals.
- Irrational numbers: Numbers that cannot be expressed as a fraction of integers. Include non-terminating, non-repeating decimals, like √2 and π.
- Real numbers ($\mathbb{R}$): The set of all rational and irrational numbers.
- Imaginary numbers: Numbers involving the square root of -1 (i).
- Complex numbers: Numbers in the form a + bi, where a and b are real numbers and i is the imaginary unit.
Basic Operations
- Addition (+): Combining quantities.
- Subtraction (-): Finding the difference between quantities.
- Multiplication (× or *): Repeated addition.
- Division (÷ or /): Repeated subtraction or finding how many times one quantity fits into another.
- Exponents (^): Repeated multiplication.
- Roots (√): The inverse of exponentiation.
Sets
- A set is a collection of distinct objects.
- Sets can be represented using roster notation (listing elements within curly brackets) or set-builder notation (defining a rule to determine set membership).
- Set operations include union (∪), intersection (∩), and complement (').
Algebraic Concepts
- Variables: Symbols that represent unknown values.
- Equations: Statements that show the equality of two expressions.
- Inequalities: Showing that one expression is more or less than another.
- Linear equations: Equations with variables raised to the power of one.
- Polynomials: Expressions consisting of variables and coefficients.
- Factoring: Breaking down an expression into simpler expressions.
- Solving equations: Finding values of variables that make an equation true.
Geometry
- Geometry studies shapes, sizes, and spatial relationships.
- Key figures include lines, angles, triangles, circles, polygons, and 3-dimensional shapes (cubes, spheres, cones).
- Measurement of angles, areas, and volumes are critical aspects of geometry.
Calculus
- Calculus deals with change and motion.
- Differentiation: Finding the rate of change of a function.
- Integration: Finding the area under a curve or accumulating quantities.
- Applications in physics, engineering, and other fields.
Important Mathematical Theorems
- Many theorems and postulates establish essential relations and properties within mathematical systems.
- Examples include the Pythagorean theorem, the Fundamental Theorem of Calculus, and various properties of logarithms and exponents.
Problem Solving Strategies
- Identifying the problem
- Defining the variables and unknowns
- Developing equations or relationships
- Applying mathematical rules and procedures
- Testing your results and solutions
- Checking your answer
Applications of Mathematics
- Mathematics is fundamental to science, engineering, computer science, economics, finance, and many other fields.
- Real-world applications involve modeling, prediction, and optimization.
- Examples of applications include simulations, calculations of physical phenomena, and design of structures.
Mathematical Reasoning
- Deductive reasoning: Proving statements based on established premises.
- Inductive reasoning: Drawing conclusions based on observations or patterns.
- Critical thinking and problem-solving are integral parts of mathematical reasoning.
