The values of the \*Jyā\* of the complementary angles vis. 67°30', 75°, 78°45', 82°30', 86°15' can be calculated by (2). The \*Jyā\* of half of these angles and again complements of these angles are calculated. By repeating this process, 24 \*Jyās\* at the intervals of 3°45' can be easily calculated. - [Previous: c8.213](https://indike.org/pramana/ins.science.bag-1979.c8.213) - [Next: c8.215](https://indike.org/pramana/ins.science.bag-1979.c8.215) - [Up: c8](https://indike.org/pramana/ins.science.bag-1979.c8) --- Source: [https://indike.org/pramana/ins.science.bag-1979.c8.214](https://indike.org/pramana/ins.science.bag-1979.c8.214) · Pramāṇa
