Summary
| Description |
English: Page from the end of Napier's 1614 logarithm table Mirifici Logarithmorum Canonis descriptio. The page cover angles between 44 degrees 30 minutes and 45 degrees 30 minutes. Adjacent to each outermost column is the sine of that angle, followed by the absolute value of the natural log of the sine. One can obtain cosines easily by reading across the page. The middle column gives the difference between the two logs, which is the natural log of the tangent function (cotangent if you reverse sign). |
