In this article I will write a simple module to display very large or very small numbers in scientific notation in a more appealing format than that used by Python.

I often use mathematical symbols in Python code which results in me scrabbling around to find the ones I need so I decided to write a simple module to simplify the process, which I will describe in this article.

In this project I will write a Python class to represent angles in various units, and provide a selection of arithmetic and comparison operators.

There is a wealth of information out there on plotting mathematical functions in Python, typically using NumPy to create a set of *y* values for a range of *x* values and plotting them with Matplotlib. In this article I will write a simple but powerful function to abstract away much of the repetitive code necessary to do this. In future articles I will show the code in use for a selection of functions.

In the first part of this article I wrote code to calculate rough estimates of square roots which enable formulas which converge on accurate square root values to do so with fewer iterations. Part 1 also included code to graph estimates to compare them to accurate values.

In this second part I'll implement some of those formulas, again graphing the results alongside definitive values.

Python provides us with a perfectly satisfactory method of calculating square roots, the math.sqrt() method, but in this pair of articles I will explore some of the ways square roots can actually be calculated from scratch. In this first article I will look into a few ways of calculating rough estimates which form a starting point or "seed" for the methods I'll examine in Part 2.

The Ancient Greek polymath Eratosthenes of Cyrene made the first serious attempt at calculating the size of the Earth. Using very simple observations and mathematics he achieved a surprisingly accurate result and in this article I will replicate his calculations in Python.

In this article I will demonstrate how to calculate the area of any quadrilateral, or four-sided figure, in Python using Bretschneider's Formula.

This is the first in a set of three articles describing how to calculate the areas of various types of quadrilaterals using the Python programming language.
