# Top 5 Most Popular Posts of March

I think I'm starting to see a trend with my posts!

The top 5 most popular posts of March are a slightly shuffled variation of my top posts from February (you can take a look at those results here: http://sk19math.blogspot.com/2013/03/popular-posts-february-2013.html).

There was a chance that one of those 5 might have dipped and allowed a new star post to rise, but alas, this was not the month for that to happen.  However, to keep things interesting, the order of these leaders this time around is slightly different, so at least I can say that there is a degree of variation here.  So, the anticipation is finally over, and I present to you my most popular stories of March:
1. Stretching and Compressing Graphs.  It was number 2 last month, but it takes the crown for March!  This post discusses all you need to know to be able to stretch and squash your graphs.

2. Converting Point-Slope Form to Standard Form.  Slipped out of the top spot for a month, but could very easily win it back in April!  Learning how to convert between point-slope form and standard form is crucial, and this post details what you need to know!  (I have also recently added a companion post about Point Slope Form, which can be found here: http://sk19math.blogspot.com/2013/02/point-slope-form.html).

3. Trigonometry - Secant, Cosecant, Cotangent.  The lesser known, yet equally useful, trig functions.  They are slight variations of sine, cosine, and tangent, so if you know those 3, you don't have far to go to understand these ones - though this post helps you figure it all out.

4. Special Angles in Trigonometry.  Special angles are easy to remember, and are extraordinarily helpful in getting your trig work done quickly.  Learn the triangles that I explain in my post, and you'll be all set!

5. Which Measure of Central Tendency to Use? Mode, Mean, or Median?  With several different ways of representing the "center" of a data set, it is frequently asked which is the best way.  In this post, you can learn some general guidelines to help you select the best way of representing your data.
