सिद्धान्तशिरोमणि: गणिताध्याय (भास्कराचार्य - ग्रहगणित, मध्यमाधिकार व स्पष्टाधिकार सटीक)

247 Verse 24. (Kujyā × Bhuja) / Karṇa = second segment of Agrajyā (Krāntijyā × Koṭi) / Karṇa = first segment of Agrajyā and Agrā = Sum of the two segments. Comm. The first statement is based on the similarity between the seventh triangle and others and the second on the similarity between the 6th and the others. Verse 25. (First segment of Agra × Bhuja) / Koṭi = Un-mandala-Śaṅku and (Krāntijyā × Bhuja) / Karṇa = Un-mandala-Śaṅku. (19) Comm. Both the statements are based upon the similarity of the sixth triangle and others. Thus un- mandala śaṅku = U.S. = (H sin δ × H sin φ) / R = = R sin δ sin φ. Verse 26. (First segment of Agrā × Koṭi) / Bhūja = Un-mandala-Śaṅku = Kujyā × Koṭi / Karṇa. Comm. The first statement is based on the similarity of the sixth latitudinal triangle and others and second that between the seventh and others. Sama-śaṅku − unmandala śaṅku = upper segment of Sama-śaṅku. Verse 27. (Agrā × Bhuja) / Karṇa = Kujyā Taddhṛti − Kujyā = upper segment of Taddhṛti.
