On Thursday September 28, 2017, Dr. Singh spoke to us about “A look at the radical side of geometry”:

Dr. Satyanand Singh introducing hist talk on radical trigonometry

Dr. Singh’s abstract can be found below. Further details can be found in the journal article “The Sine of a Single Degree” by Travis Kowalski, which appeared in the November 2016 issue of The College Mathematics Journal; the pdf is available for download on JSTOR here.

September 28, 2017: Dr. Satyanand Singh: “A look at the radical side of trigonometry”
Abstract: In this presentation we will illustrate by geometric and algebraic means how one can calculate the exact values of sin(3n◦), where n takes on integral values in the interval 0 ≤ n ≤ 9. In this journey we will encounter different shapes such as
and travel along a complex path to derive a multitude of ways to represent sin(1◦). These notions readily extends to other trigonometric functions.
