I make short, to-the-point online math tutorials. I struggled with math growing up and have been able to use those experiences to help students improve in math through practical applications and tips.

In this video I present a set of problems to help prepare for learning about rational functions in precalculus. While rational functions is explored in Algebra 2 I decided to make it a separate unit ...

This contribution is part of the special series of Inaugural Articles by members of the National Academy of Sciences elected in 2024. Analytic combinatorics in several variables estimates coefficients ...

Abstract: This paper presents a modified rational function modeling technique for high speed circuits. It models the scattering parameters (S-parameters) of high speed circuits with modified rational ...

Note: The article usage is presented with a three- to four-day delay and will update daily once available. Due to ths delay, usage data will not appear immediately following publication. Citation ...

Abstract: This paper presents a new functional network which is based on rational function. A learning algorithm of rational functional network is proposed, the learning of functional network ...

Add a description, image, and links to the rational-functions topic page so that developers can more easily learn about it.

Accurate line models are essential for investigating transient analysis in power systems (Zhou et al., 2021; Hu et al., 2022; Lei et al., 2023). The impedance of transmission lines varies with ...

Rational Tracer (Ratracer) is a tool to simplify complicated arithmetic expressions using modular arithmetics and rational function reconstruction, with the main idea of separating the construction of ...
