We take a look at aspect ratio - specifically, how to size an image, video or other object of one size to fit it into a container of another size. Support Coding Math: http://patreon.com/codingmath Source Code: http://jsbin.com/lovido/2/edit?js,output

Let's take a look at what "dot product" is - a couple of ways to calculate it, and some uses for it. Support Coding Math: http://patreon.com/codingmath Source Code: http://github.com/bit101/codingmath http://jsbin.com/hutisoq/edit?js,output

A quick, fun video on a technique known as circle packing. Or at least one take on the technique.

Back to School Special. This short series will discuss pseudo random number generators (PRNGs), look at how they work, some algorithms for PRNGs, and how they are used.

A quick intro to the QuickSettings.js library. Super useful for experimenting with algorithms and changing values on the fly. Find it here: https://github.com/bit101/quicksettings

This is too much fun to play with. Need to stop myself sometimes, so I can get some actual progress on the code. Support Coding Math: http://patreon.com/codingmath

A very early demo of a project I'm working on. This is an extension of the code in Episode 50, IFS Fractals. It will allow you to create rule sets consisting of 2d transforms, change all the parameters and weight, and see the results in real time. All HTML5 Canvas and JavaScript. Still a lot of work to do, but it's still really fun to play around with it. Support Coding Math: http://patreon.com/codingmath

Combining everything from episodes 47 - 49 to create some cool fractal images. Support Coding Math: http://patreon.com/codingmath Source Code: http://github.com/bit101/codingmath http://jsbin.com/fevira/1/edit?html,css,js,output

This week we wrap up our discussion of Matrix Math with some real world examples of translating, rotating and scaling using matrices, both in Canvas and straight CSS.

In part one of this series, we discuss the basics of matrices for scaling, rotating and translating 2d points and objects, including multiplying and adding matrices. Support Coding Math: http://patreon.com/codingmath Source Code: http://github.com/bit101/codingmath

Weighted random functions allow you to randomly choose between multiple options, while specifying the exact odds of getting any one option.
