Fundamental Concepts of Mathematics

Study Notes

Fundamental Concepts

Mathematics is a formal system of logical reasoning using symbols and rules to represent and manipulate quantities, relationships, and structures.
It includes arithmetic, algebra, geometry, calculus, and more specialized fields.
Key concepts include:
- Sets: Collections of objects defined by shared properties.
- Logic: Rules of reasoning to determine argument validity.
- Functions: Relationships between input and output values.
- Numbers: Types like natural numbers, integers, rational numbers, irrational numbers, and complex numbers, each with specific properties.
Mathematical notation is a standardized language for complex ideas.
Mathematical proofs establish theorem validity through logical deduction.

Arithmetic

Arithmetic deals with basic number operations.
Basic operations: addition, subtraction, multiplication, and division.
Arithmetic properties: commutativity, associativity, distributivity, and identity elements.
Order of operations (PEMDAS/BODMAS) dictates expression evaluation sequence.

Algebra

Algebra extends arithmetic by using variables for unknowns.
Equations and inequalities are statements of equality or inequality with variables and constants.
Solving equations and inequalities finds variable values satisfying conditions.
Polynomials are expressions with variables and constants combined through operations and non-negative integer exponents.
Factoring expresses polynomials as products of simpler polynomials.
Systems of equations involve multiple equations solved simultaneously.

Geometry

Geometry studies shapes, sizes, positions, and space properties.
Basic shapes: points, lines, angles, planes, polygons, and circles.
Euclidean geometry is a system based on axioms about points, lines, and planes.
Non-Euclidean geometries exist with different parallel postulates.
Coordinate geometry uses coordinates to describe geometric objects in a plane or space.
Transformations include translations, rotations, reflections, and dilations.

Calculus

Calculus deals with rates of change and accumulation of quantities.
Differentiation finds function rate of change.
Integration finds function accumulation over an interval.
Applications include area, volume, velocity, and acceleration calculations in physics and engineering.
Limits are fundamental concepts defining continuity and derivatives.
