This is probably the last of three articles on how piecewise-linear functions could be used as a helpful on-ramp to the big ideas in calculus. In the first article, we saw how it’s possible to develop ...

Abstract: This article is about a categorical approach modelling a simple term calculus, named Ѕℓλ-calculus. This is the core calculus underlying the programming language ЅℓλPCF conceived in order to ...

What is Xi? Why create it? I chose Xi after the 14th letter of the greek alphabet, it is a personal favorite letter of mine and doesn't seem to get much recognition or love from the math community, so ...

Abstract: In part I of this paper, the development of a course on linear signals and systems is presented, based on an infinitesimal calculus model, called MicroCalculus. Such a calculus model allows ...

This paper provides inference methods for best linear approximations to functions which are known to lie within a band. It extends the partial identification literature by allowing the upper and lower ...

This course is compulsory on the BSc in Finance. This course is available on the BSc in Accounting and Finance, BSc in Econometrics and Mathematical Economics, BSc in Economics, BSc in Philosophy and ...

Teaching students to identify linear and nonlinear functions is an essential aspect of any maths curriculum. This knowledge provides the foundation for understanding more advanced topics such as ...
