1940 book for navy cadets. Good refresher of trig. - Rumata - 12-12-2019
Gentlemen, found an old 1940 book US Naval Academy, Plane and Spherical Trigonometry , by Kells, Kern, and Bland. Admittedly, majority of the book is trig and exercises, but there are a few spherical trig items which will be helpful if the battery is dead. What I personally like about this book, it does not consider its reader too knowledgable and therefore explains everything to the bone. Which is as a refresher I personally found helpful. Just for information, of course. ;> ;>
Thank you
