In 2004, two mathematicians hypothesized a powerful kind of sandwich. They were studying graphs, which are collections of points (called vertices) and lines (called edges). Graphs might represent ...

The first handheld graphing calculator, the Casio fx-7000G, appeared in 1985. Since then, graphing calculators have become a common – and controversial – tool for learning mathematics. These devices ...

Terri Oda is a mathematician who now works in computer science. She is also female. Weird, right? When people told her women were biologically unsuited to math, she used to draw a graph for them on ...

Math Notes is a unique feature that was first introduced in iPadOS 15 and iOS 15. It brought several intuitive tools for solving math problems, such as auto-completing equations and graphing functions ...

Jacob Holm was flipping through proofs from an October 2019 research paper he and colleague Eva Rotenberg—an associate professor in the department of applied mathematics and computer science at the ...

David Conlon and Asaf Ferber have raised the lower bound for multicolor “Ramsey numbers,” which quantify how big graphs can get before patterns inevitably emerge. “There is no absolute randomness in ...

Graph theory examines mathematical structures in which objects are represented as vertices connected by edges. It provides the language and tools to model networks in computer science, biology, social ...

Concepts covered in this course include: standard functions and their graphs, limits, continuity, tangents, derivatives, the definite integral, and the fundamental theorem of calculus. Formulas for ...
