I guess I’ve been a bad blog keeper who hasn’t posted since September. I truly thought that I would get back into my rhythm of Friday morning posts, but sometimes life happens. I feel like this calls for another post on advice to highschoolers, but let’s keep that aside for now.

A special friend read my blog, and with such enthusiasm she asked me to continue, so how could I resist? She even asked me to post some of my poems, and although I thought poetry wouldn’t fit the theme of my blog, I figure it also counts as an art. With that being said, I would like to segue into a new series of posts with my very first limerick dedicated to math!

I hope you enjoy 🙂

This limerick is dedicated to the trigonometric identity sin²θ + cos²θ = 1. If you remember the unit circle from precalculus, you may know that the radius of the circle is one, and any right triangle drawn by creating a perpendicular line from a point on the circle to the x-axis has a hypotenuse of length 1. In that case sin and cos represent the lengths of the two legs, and applying Pythagorean theorem results in this identity.

If you’re the special friend reading this then, HI! If not, then also HI! Hope you guys stay happy and healthy (and mathemagical).
