# Top 5 Most Popular Posts of February 2013

Another month has come and gone, so in trying to maintain my new year's resolution, here is my monthly summary of my top 5 most popular posts of February 2013.  This is tabulated simply from the number of visitors each page on my blog receives.  I have recently started a Facebook page for my site as well, so eventually I would like to have these "best of" posts reflect the most shared or most liked content.  For now though, I don't have enough traffic to compile meaningful stats.

This is a great opportunity for anyone to catch up on some of my more popular pages, if they haven't been following along from the very beginning... which I'm sure is most people.  ;)  So, here we go.  My top 5 most popular posts of the month!

1. Converting Point-Slope Form to Standard Form.  This is easily my most visited post in the history of my site, and this month it was back on top again.  Choosing the proper way to express your equation of a line is important, so learning how to convert between point-slope form and standard form is crucial!

2. Stretching and Compressing Graphs.  When you first learn how to graph functions, you are amazed that numbers actually mean something.  Then, with this concept, you add on top of that the ability to modify your image by stretching it or squashing it.  This post discusses the all you need to know to perform these modifications on your graphs.

3. Trigonometry - Secant, Cosecant, Cotangent.  These trigonometric functions are the less famous variants of the ubiquitous sine, cosine, and tangent.  There isn't anything special about them, you just have to understand their connection to the main three functions.  In this popular post, I explain them and show you what their symbols are so that you won't be confused anymore!

4. Which Measure of Central Tendency to Use? Mode, Mean, or Median?  This is one of the first things that is discussed in statistics courses: how to measure the center of a data set.  Of course, there are different ways of representing the center.  So, this post gives some pointers on which measure is appropriate for various types of data.

5. Special Angles in Trigonometry.  There are a couple of special angles that are very important to trigonometry.  They are easy to memorize, and will make other trig work seem much easier.  They are all based on triangles, and if you follow the tips in this post, you'll have all you need to know to tackle trigonometry questions.
