Do you know that some limits from the limit theory are considered “wonderful”? Actually, I’ve never met such a term in English literature, but it’s widely known in post-soviet countries. In Russian, it’s written as “замечательные пределы” [zamechatelnye predely] and these limits are even studied in universities on this topic. …

Gauss’ Law (for magnetism) — Maxwell’s equations are, and I quote Wikipedia on this one “A set of coupled partial differential equations that, together with the Lorentz force law, form the foundations of classical electromagnetism.” Well, Wikipedia’s got it right for the most part. They are coupled. They are differential equations. And of course, they…

Concavity describes the rate of change of a function’s derivative. If f’ is increasing then the graph is concave up, and if f’ is decreasing, then the graph is concave down. To test for concavity, we have to find the second derivative and determine whether it is positive or negative. …

A guide on 3 common algebra functions used in data science and data analysis, with worked examples using cats 😺 1. Linear Functions Linear functions are those whose graph is a straight line in the coordinate plane. It has the following form where x is the independent variable (also called the input) and…

WHAT IS STATISTICS? Statistics can also be defined as the science of collecting, analyzing, and interpreting data. Statistics is a field that has been existing for a long time now and it’s also a must-know field for every data scientist. It involves the study of data to obtain actionable insights that will be…
