Jya Ganitha means Trignometry. The equation for Koti is different. It is Kotijya by Trijya or Adjacent Side by Hypotenuse ( the modern Cos ). As per Indian Learning it was Aryabhata, one of the greatest mathematicians ever, who first computed the celestial longitudes of planets ( Aryabhato Graha Ganitham ).
Brahmagupta, in his mathematical treatise, the Brahmasphuta Siddhanta used the word Jya which means 5 degrees of a 360 degree circle which is the Zodiac, which is the Ecliptic. Suppose a planet has traversed 42 degrees in the first Oja Pada ( From Aries to Gemini end ).The Bhuja is 42 degrees and the Bhujajya is the 9th Jya or the 9*5 th degree. Bhujajya by Trijya is Opposite Side by Hypotenuse or the modern Sine. So Bhuja is 42 and Bhujajya is sin(42).

In the Mighty Circle of Light, the Kala Chakra / The distance traversed is Bhuja called / Koti is the untraversed degree ! / Oja Pada means the Odd Quadrant / In the next Yugma Pada. 90 to 180 / The traversed Degree is Koti / And Bhuja, the untraversed ! / This is the Equation of Bhuja !
In the Great Circle of Light which is 360 degrees, ( the Bha Chakra, the Kala Chakra, the Zodiac ), the first 90 degrees are Oja Pada ( Odd Tri Signs ) and the next 90 degrees are Yugma Pada ( Even Tri Signs ).
The Equation of Bhuja
The degrees traversed by a planet is called Bhuja and the degrees yet to be traversed by a planet is called Koti in an Oja Pada. In a Yugma Pada, the degrees traversed by the planet is called Koti and the degrees yet to be traversed by a planet is called Bhuja. In other words, the degrees traversed by a planet is the same in the first 0 – 90 degrees and in the second Pada, it is 180 – degrees traversed. In the 180-270 degrees arc, it is distance traversed – 180 degrees and in the 270-360 degrees arc, it is 360 – distance traversed. This is known in Vedic Astronomy as the equation of Bhuja or Sine. Bhujajya is radius multiplied by modern Sine.
