Hints, theoretical, elucidatory, and practical, for the use of teachers of elementary mathematics, and of self-taught students This book, "Hints, theoretical, elucidatory, and practical," by Olinthus Gregory, is a replication of a book originally published before 1840. It has been restored by human beings, page by page, so that you may enjoy it in a form as close to the original as possible.
Olinthus Gilbert Gregory (29 January 1774 – 2 February 1841) was an English mathematician, author and editor.
He was born on 29 January 1774 at Yaxley in Huntingdonshire. Having been educated by Richard Weston, a Leicester botanist, in 1793 he published a treatise, Lessons Astronomical and Philosophical. Having settled at Cambridge in 1796, Gregory first acted as sub-editor on the Cambridge Intelligencer, and then opened a booksellers shop. In 1802 he obtained an appointment as mathematical master at the Royal Military Academy, Woolwich through the influence of Charles Hutton, to whose notice he had been brought by a manuscript on the Use of the Sliding Rule; and when Hutton resigned in 1807 Gregory succeeded him in the professorship. Failing health obliged him to retire in 1838, and he died at Woolwich on 2 February 1841.
