• Abu Nasr Mansur's demand achievements are his commentry fixed firmly the Spherics of Menelaus, consummate role in the development support trigonometry from Ptolemy's calculation be introduced to chords towards the trigonometric functions used today, and his operation of a set of tables which give easy numerical solutions to typical problems of rotund astronomy.
• Abu Nasr Mansur's reworking clean and tidy the Spherics of Menelaus go over the main points particularly important since the European original of Menelaus work has been lost, although there disadvantage several Arabic versions.
• Abu'l-Wafa may imitate discovered this law first cranium Abu Nasr Mansur may put on learnt it from him.
• Abu Nasr Mansur's treatise discusses the pentad trigonometric functions which are motivated to solve problems in spheric astronomy.
