Revisiting Khan Academy After Four Years

It was four years ago when I discovered Khan Academy, which as far as I can remember a Youtube channel with more than a thousand videos. If I am not mistaken, it was only then managed by Salman Khan, it’s founder.

A year ago or two, when I searched the internet, I learned that Khan Academy has already its own website and it is run already by a group of educators. Three weeks ago, I started using the website. As of this writing, I have already watched 29 videos (oh yes, I watched them from start to end) and earned 56,340 points. 🙂  » Read more

Hundreds of Combinatorics Video Lectures

If you are taking mathematics courses related to combinatorics or probability, I found a page from UCLA containing hundreds of video lectures on the said subjects. It is a collection of lectures from 1993 up to the present and includes lectures from famous mathematicians such as Terence Tao.

For more free video lectures, visit the All for Free page of Math and Multimedia. It also contains posts which links to hundreds of free ebooks and software.

Math Expressions and Graphs in Google Docs with g(Math)

Last week, I wrote about a tutorial on how to create math expressions in a Google Forms using Latex. Embedding of Latex in Google Docs documents can be made using the new g(Math) Google Docs Add On. Although Google Docs has a built in equation editor, the addition of Latex through g(Math) can make embedding of more complicated equations possible.

In addition to Latex, you can also create graphs using g(Math). Once you have added this add on, you can create graphs using the side bar of your Google Docs window.

Watch John McGowan, creater of g(Math), demonstrates how to use g(Math) on Google Docs.

For those who are not familiar with Latex, it is a typesetting system used to create scientific documents. It can also be used to create complicated math expressions. You can read my introduction and brief tutorial about latex in case you don’t know about it.
