Description

Elementary Trigonometry by H.S.Hall and S.R.Knight is a reproduction of a book by the same name, published before 1923. Despite minor impairments of errant marks, substandard images or missing pages which were the outcome of scanning or part of original manuscript, the book is yet considered to be culturally significant. This is why, it has been elected to be reprinted because of our commitment to preserving historical print works all around the world. We are grateful for the understanding of our esteemed readers for erroneous reproduction in the preservation process and hope the learning is still fruitful and enjoyable.
