The Fifteen Problems

Abstract

The seven great circles which are frequently employed in deriving various results in this chapter are listed in Table 10.1. These circles are indicated by solid lines in Figure 10.1. Three more circles which are referred to later in the chapter are indicated by dashed lines. In Table 10.1, the second column gives the names of the circles in Sanskrit. The third column gives their modern equivalents. In the last column we have listed the poles (visible ones with ref. to Figure 10.1) of these great circles.
