Create Latex Documents with Lyx

If you are creating a lot of scientific documents or numerous documents that contains math equations, then you might want to check out Lyx. I have been using Lyx for a week and I really like it.

Lyx is a free and open-source document processor built on top of the Latex typesetting system. It has the power of Latex, so it can be used to create books, notes, theses, and academic papers. It is free and is available for Windows, Mac OS X, Linux, UNIX and OS/2.


Lyx has a lot of great features, some of which are listed below.

  • Graphical user interface with menus
  • Automatically numbered headings, titles, and paragraphs, with table of contents
  • Copy paste to and from Latex source code
  • Bibtex support
  • WYSIWYG for cropping, rotation, and scaling of images
  • WYSIWYG table and math editors
  • Export to Docbook, SGML, XHTML, and plain text

How to Use Latex on Facebook

To all math teachers, mathematicians, and math enthusiasts who are also Facebook users, it is now possible to use Latex on Facebook. All you have to do is to use Google Chrome as a browser and install the Latex for Facebook Extension.

Until Facebook integrates latex into its system, I think this one is very good to use. So far so good, I have no complains about it.

To use latex in Facebook, just put the $ sign before and after the latex code. The equation below is an example of an expression image generated by latex. » Read more

The Best Free Math Tutorial Website

If I were to recommend a free mathematics tutorial website, I would definitely choose the Art of Problem Solving. The Art of Problem Solving is a website where students, teachers, mathematicians and math enthusiasts meet online to discuss problems in mathematics.  Shown below is the screenshot of their home page.

The most popular feature of the the Art of Problem Solving website is Art of Problem Solving Forum. I had a firsthand experience with the Art of Problem Solving Forum when I was still studying. Sometimes, I had to seek help for topics that I did not understand or a problem that I could not solve, and the Art of Problem Solving had really helped me a lot.

The reasons why I chose AOPS over other math help websites are listed below.

  1. Quick Response. When you ask questions in other websites, it would probably take a long time for them to respond. AOPS Forum, on the other hand, has more than 74,000 members as of this writing.  Since there are many members around the world, there is a very good chance that your questions would be answered immediately.
  2. Wide Variety of Topics. AOPS problems ranges from elementary school mathematics to college mathematics.  There are also sections for mathematics competitions such MathCounts, AMC and other well-known contests. College topics include calculus and real analysis, differential geometry, topology and linear algebra and many more.
  3. Latex Support. AOPS supports latex coding unlike other websites. Latex is used to embed mathematical expressions such as c = \sqrt{\displaystyle\frac{a^2 + b^2 + c^2}{3}} \geq \displaystyle\frac{a+b+c}{3} on websites, blogs and wikis. If you do not know about Latex, I have created a Latex tutorial here and here.
  4. Lots of Problems. AOPS has 1, 673, 927 topics (or problem posts) as of this writing. There are also problem solving marathons (click here to see example) where one post contains hundreds of problems.
  5. Own Wiki and Blogs. AOPS has its own wiki mostly contributed by users.  Many users have also registered their blogs in AOPS.
  6. Online Math Classes. AOPS has free online classes called Math Jams where classes are conducted synchronously.
  7. Math Contests Problem Archives. AOPS has archived mathematics competitions around the world. Some of the famous contests such as the International Mathematics Olympiad.

Art of Problem Solving also offers advanced mathematics online classes and they have published several books.
