Spherical Trigonometry ,Capt Subramaniam
Like the other books in the Nutshell Series, Capt. H. Subramaniam have attempted to simplify the subject to make it easy and interesting. Spherical trigonometry is a `servicing subject’ i.e., one which enables a student to under-stand another subject. Spherical trigonometry is studied by mariners so that they can understand the practice and principles of navigation. Capt. H. Subramaniam have carefully divided the subject into parts so that, after studying for about three quarters of an hour, the student is given an exercise to work to test the knowledge gained by him in that chapter.
