My talk for Wednesday December 7th will be about the history of trigonometry along with some mathematicians associated with trig, and how trigonometry can be used in Astronomy. By reading the article by Herb Silverman called, Trigonometric Identities through Calculus*,* from *The College Mathematics Journal *Vol. 21, No. 5 (Nov., 1990), p. 403, I was interested in how trigonometry came about and was surprised to find out its use in astronomy. More about this will be mentioned tomorrow. I hope you all find it interesting and be able to use this information someday!
