Study Notes
- Mathematics is the abstract science of number, quantity, and space.
- Mathematics can be used as a pure science, or applied to other disciplines.
Arithmetic
- Arithmetic involves studying numbers, mainly the properties of traditional operations like addition, subtraction, multiplication, division, exponentiation, and extraction of roots.
- A field is any set of objects upon which all of these operations can be performed.
- Arithmetic operations follow a specific order of operations: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction (PEMDAS).
Algebra
- Algebra is a branch of mathematics that generalizes arithmetic, using variables to represent numbers.
- Elementary algebra deals with solving equations and inequalities.
- Linear equations can be solved by isolating the variable on one side.
- Quadratic equations can be solved by factoring, completing the square, or using the quadratic formula.
- Abstract algebra extends the concepts found in elementary algebra to more general structures, such as groups, rings, and fields.
- Boolean algebra operates on binary values (0 and 1) and is fundamental to digital logic.
Geometry
- Geometry focuses on the properties and relations of points, lines, surfaces, solids, and higher dimensional analogs.
- Euclidean geometry, based on Euclid's axioms, deals with the properties of space, distances, angles, and shapes.
- Analytic geometry uses algebraic techniques to study geometric problems, often using coordinate systems like the Cartesian coordinate system.
- Trigonometry studies the relationships between the sides and angles of triangles, particularly right triangles, and uses trigonometric functions such as sine, cosine, and tangent.
- Differential geometry employs calculus to study the properties of curves and surfaces.
- Topology studies the properties of geometric objects that remain unchanged under continuous deformations such as stretching and bending.
Calculus
- Calculus is concerned with the study of continuous change.
- Differential calculus deals with the rate of change (derivatives) and slopes of curves.
- Integral calculus deals with the accumulation of quantities (integrals) and the areas under and between curves.
- The fundamental theorem of calculus connects differentiation and integration.
- Calculus is used in physics, engineering, economics, and computer science.
Statistics and Probability
- Statistics involves the science of collecting, analyzing, presenting, and interpreting data.
- Descriptive statistics focuses on summarizing and presenting data through measures such as mean, median, mode, variance, and standard deviation.
- Inferential statistics involves drawing conclusions and making predictions based on a sample of data.
- Probability theory is the study of randomness and uncertainty, providing a framework for calculating the likelihood of events.
- Random variables are variables whose values are numerical outcomes of a random phenomenon.
- Probability distributions describe the likelihood of different outcomes for random variables.
- Common distributions include the normal distribution, binomial distribution, and Poisson distribution.
Discrete Mathematics
- Discrete mathematics studies mathematical structures that are discrete rather than continuous.
- Logic deals with reasoning and proof techniques, and it is fundamental to computer science.
- Set theory deals with collections of objects and operations on them.
- Graph theory studies graphs, which are mathematical structures used to model pairwise relations between objects.
- Combinatorics is concerned with counting and arranging objects.
Number Theory
- Number theory is a branch of mathematics devoted primarily to studying integers and their properties.
- Prime numbers, divisible only by 1 and themselves, are fundamental to number theory.
- Divisibility rules provide shortcuts for determining whether a number is divisible by another number.
- Modular arithmetic deals with the remainders of numbers after division.
- Cryptography relies heavily on number theory for secure communication.
Mathematical Analysis
- Deals with the rigorous study of calculus concepts.
- Focuses on limits, continuity, differentiation, integration, and infinite series.
- Real analysis studies real numbers and functions.
- Complex analysis extends calculus to complex numbers.
- Functional analysis studies vector spaces and linear operators.
Numerical Analysis
- Develops algorithms for solving mathematical problems.
- Approximates solutions to problems that are difficult or impossible to solve analytically.
- Key areas: root finding, interpolation, numerical integration, and solving differential equations.
