Study Notes
- Mathematics is the study of topics such as quantity (numbers), structure, space, and change
- It has no generally accepted definition
History
- Mathematical study began first in ancient cultures
- As a formal science, mathematics was developed by the ancient Greeks
Branches of Mathematics
- Quantity: Mathematics began with numbers, familiar to nearly all humans
- Structure: Deals with the properties of objects that do not depend on quantity
- Space: Studies the relationships between objects
- Change: Describes how quantities change over time
Mathematical Notation
- As mathematics developed, abstract symbols became commonly used
- Notation allows mathematics to be more efficient
- A mathematical expression is a sequence of symbols that can be evaluated
- Conventions dictate the meaning of mathematical symbols
- Symbols vary in different dialects, or areas in which symbols are used
- The equals sign represents the equality of two expressions
Numbers
- Important number types are natural, integer, rational, irrational, and complex
- Natural numbers are the familiar counting numbers
- Integers are natural numbers with their negatives and zero
- Rational numbers are ratios of two integers
- Real numbers include all rational numbers, together with irrational numbers
- Complex numbers are numbers that include the imaginary unit i.
Equations
- An equation is a problem that can be solved for one or more unknowns
- Equations consist of two expressions separated by an equals sign
- A general equation is one which uses symbols to represent arbitrary values
- Types of equations include algebraic, differential, and integral
Theorems
- A theorem is a statement that has been proven to be true
- Theorems are derived from axioms, which are statements assumed to be true
- A conjecture is a statement that is proposed to be true, but has not been proven
- Theorems can be proven under certain axioms
Calculus
- Studies continuous change
- Has two main branches:
- Differential calculus is concerned with the instantaneous rate of change of quantities
- Integral calculus is concerned with the accumulation of quantities
- Calculus is used extensively in physics, engineering, economics, and computer science
Algebra
- Algebra is the study of mathematical symbols and the rules for manipulating these symbols
- Elementary algebra is an essential part of mathematics
- Abstract algebra studies algebraic structures such as groups, rings, and fields
Geometry
- Geometry is one of the oldest branches of mathematics
- Initially concerned with practical problems such as surveying
- Euclidean geometry studies shapes, lines, angles, surfaces, and solids
- Modern geometry includes many non-Euclidean geometries
Trigonometry
- Trigonometry studies relationships between angles and sides of triangles
- Trigonometric functions such as sine, cosine, and tangent are used to describe these relationships
Discrete Mathematics
- Discrete mathematics deals with mathematical structures that are fundamentally discrete
- It includes logic, set theory, combinatorics, graph theory, and cryptography
- Discrete mathematics is used extensively in computer science
Mathematical Proof
- A mathematical proof is an argument that demonstrates that a statement is true
- Proofs use logic and previously-established results to arrive at a conclusion
- Proofs rely on axioms and rules of inference
- Proofs can be direct, indirect, or by contradiction
- Proofs can also use mathematical induction
Statistics and Probability
- Statistics is concerned with collecting, analyzing, and interpreting data
- Probability is the study of chance and uncertainty
- Both are used in decision-making
Topology
- Studies properties that are preserved through deformation
- Has connections to analysis, geometry, and algebra
Applications of Mathematics
- Used in nearly all fields
- Used in the natural sciences, engineering, medicine, finance, and the social sciences
- Essential in computer science and information technology
- Used for creating models, simulations, and predictions
Mathematical Modeling
- Mathematical models are used to study real-world problems
- Models simplify complex systems
- Models can be used to make predictions
- Results can be validated through comparison with observations
Mathematical Finance
- Uses mathematical models for financial markets
- Used for pricing derivatives, managing risk, and portfolio optimization
Mathematical Physics
- Applies mathematics to problems in physics
- Models help to study mechanics, electromagnetism, and thermodynamics
Computational Mathematics
- Deals with using computers to solve mathematical problems
- Includes numerical analysis, symbolic computation, and scientific computing
Set Theory
- Branch of mathematical logic that studies sets
- Sets are collections of objects
- Set theory is foundational for many areas of mathematics
Logic
- Logic is the study of reasoning
- Mathematical logic applies formal logic to mathematics
- Used in computer science for algorithm design and verification
Mathematical Analysis
- Rigorous treatment of calculus
- Includes real analysis and complex analysis
- Used to study limits, continuity, differentiation, and integration
Combinatorics
- Counts arrangements of objects
- Used in computer science and operations research
Graph Theory
- Studies graphs, which are collections of nodes and edges
- Used in computer science, social networks, and operations research
Game Theory
- Studies strategic interaction between individuals
- Used in economics, political science, and biology
Mathematical Optimization
- Finds best solution from a set of available alternatives
- Used in engineering, economics, and operations research
