Exact Expressions for Trigonometric Functions

Abstract

Herman Robinson (7 Apr 1912 to 10 Oct 1986) was a scientist at the UC Berkeley Radiation Lab in Berkeley, CA. He worked there from 1945 until he retired in 1973. Herman was a chemical engineer by training, but his interests and skills ranged over a variety of science, math, and technology topics. He enjoyed "tinkering" with mathematical calculations after he retired with the Wang 720c calculator he purchased for himself, having used one at the office. In 1990, I discovered that he was my biological father.
