On Pertrigonometric Functions
Pertrigonometric functions are modifications of the three primary trigonometric functions. Unlike the familiar sine, cosine, and tangent functions, the “pertrig” functions include triangle perimeter in their righttrianglebased definitions, which are given in the bulleted list below. The longer form of … Continue reading

Trigonometric StainedGlass Windows
To make the virtual “painting” above, I plotted simple and moderatelycomplex trigonometric functions on a single coordinate plane, as shown below, using Geometer’s Sketchpad. I then erased all the text, etc., copiedandpasted a screenshot into MSPaint, and used that program … Continue reading

The 98190 Triangle
In a previous post (right here), I explained the 187290 triangle, derived from the regular pentagon. It looks like this: I’m now going to attempt derivation of another “extraspecial right triangle” by applying halfangle trigonometric identities to the 18º angle. After … Continue reading

Circumsinusoidal Regions, Part Two
[Note: If you haven’t yet read part one, it is recommended to read it first, before reading this part. Part one is the most recent post here, before this one.] In part one, a special circumsinusoidal region was described, bounded … Continue reading
