Key To Bradburys Elementary Geometry And Trigonometry Classic Reprint PDF Download

Excerpt from Elementary Trigonometry: Plane and Spherical Among the methods proposed for the solution of sphér. Ical triangles, attention may be called to the elegant ones furnished by the Gaussian equations. Notwithstanding the ambiguity attaching to the square roots of which these equations are composed, the results present but little difficulty of interpretation, as the examples in the last chapter show. In case, however, of any perplexity, the simple and direct method of solution based on the funda mental equations can be employed to remove it. By using three-place natural functions, a rough approximation can be made, which will show the general shape of the required triangle, and, except in extreme cases, give the values of the required parts within a fraction of a degree.
