The Suns mean longitude

Rest mean Anomaly
325. 21459
Whose complement to a Circle
34. 78541
is the angle A M E in the Ellipsis.
And the complement of A M E to a semicircle is the angle E M H 145. 21459.
The side M E

The side M H

Tang. ½ Differ
16. 81799
9. 4803814
Differ
57471 is the angle M E H.
Difference doubled
1. 14942 is the angle M B H
3 The mean Anomaly being above 180 deg. the Aequation found must be added to the sunsmeane longitude, so have you the Suns true place.
