Abstract

The object of this paper is to determine the values of x and z for a given value of sin 2y, by the methods of Elementary Geometry. The rationalised trigonometric form stated above will be found to be best adapted for this purpose. The method of solution by the use of Elliptic Functions is briefly indicated at the end of the paper.
