...any other course (except the two as AB and EA meeting on the reference meridian) is equal to the DMD of the preceding course, plus the departure of that course, plus the departure of the course itself. Of CD it is equal gC+/D=(gC+aff)+ bC+cD, since (aB=fk)+(bC=kc)+cD=fD\ Therefore, comparing the quantities,... | |
