Napier's rule spherical triangle
Witryna19 sie 2024 · SPHERICAL TRIANGLES. 9 triangle are proportional to the angles subtended at the centre of the sphere, we may use a, b, cto denote the numerical values of those angles in terms of any unit. We shall usually suppose both the angles and sides of a spherical triangle expressed in circular measure. (Plane Trigonometry, Art. 20.) 21. WitrynaSolution of right spherical triangle. With any two quantities given (three quantities if the right angle is counted), any right spherical triangle can be solved by following the Napier’s rules. The rules are aided with the Napier’s circle. In Napier’s circle, the sides and angle of the triangle are written in consecutive order (not ...
