Fourier Transform
The Fourier transform is a mathematical tool that rewrites a signal or function in terms of frequencies, making hidden patterns in sound, images, waves, data, and physical systems easier to analyze.

Topics
Combinatorics
Combinatorics studies how objects can be counted, arranged, selected, grouped, and structured, often in finite or countable settings.
Abstract algebra
Abstract algebra studies operations and structures such as groups, rings, and fields, revealing patterns behind symmetry, equations, and number systems.
Differential equations
Differential equations describe systems by relating quantities to their rates of change, making them central to motion, growth, fields, waves, and feedback.
Discrete mathematics
Discrete mathematics studies countable structures such as sets, graphs, sequences, logical statements, and algorithms rather than continuous change.
Logic
Logic studies valid reasoning, using precise rules to analyze arguments, statements, proofs, truth, and consequence.
Statistics
Statistics turns data into evidence by describing variation, estimating unknown quantities, testing claims, and measuring uncertainty.
Probability
Probability studies uncertainty by assigning mathematical structure to random events, outcomes, likelihoods, and long-run patterns.
Calculus
Calculus studies change and accumulation, using limits, derivatives, and integrals to describe motion, growth, area, optimization, and continuous systems.
Linear algebra
Linear algebra studies vectors, matrices, and linear transformations, giving a compact language for equations, geometry, data, and computation.
Number theory
Number theory studies integers and the patterns behind divisibility, primes, remainders, equations, and arithmetic structure.
Set theory
Set theory studies collections of objects and gives mathematics a precise language for membership, comparison, infinity, and structure.
Topology
Topology studies properties of space and shape that survive continuous stretching, bending, and deformation without cutting or gluing.
Graph theory
Graph theory studies relationships as points connected by lines, turning networks, routes, dependencies, and choices into mathematical objects that can be analyzed.
Photomath
Photomath is a popular math website and app that helps users solve math problems, understand homework, and review step-by-step explanations.
Mathway
Mathway is a popular math website that answers algebra, calculus, graphing, and other math problems with calculator tools and step-by-step explanations.
Symbolab
Symbolab is a popular math website for step-by-step solving, online calculators, practice problems, and support across algebra, calculus, statistics, geometry, and chemistry.
Desmos
Desmos is a popular math website known for free online graphing, scientific, geometry, and matrix calculators used by students, teachers, and math learners.
Mathematics
Mathematics studies patterns, quantities, structures, spaces, change, and uncertainty through precise definitions, symbolic language, logical proof, computation, and models. It is both a creative field of abstract ideas and a practical toolkit behind science, technology, finance, engineering, and everyday decisions.
Game theory
Game theory is the mathematical study of strategic situations, where each participant's best choice depends on what others do, helping explain conflict, cooperation, bargaining, markets, politics, biology, and technology.
