While I was reading the Ganita Nirnayam, the Bible of all Keral Ganiths, I could not fully understand , as it was using tough Mal and Sanskrit words,
Words like Chyuti Samskaram, Parama Mandkarnam, Laghu Mandakarnam, Natasam and Digamsam bamboozled me.
There was a 10 page mathematical table called Sparsha Jyakkal.
Jya meant 5 degrees of a Circle or Ellipse and the Zodiac was made up of 72*5 = 360 Jyas.
In this Math Table, math value for every 5 degree was given. I thought if I create a data file out of it, I will have to sit for a Week, doing hard work.
I tested for Sine, Cos, bu the Table did not budge. But it took when I put Tan. Tan is Sparsna Jyakkal !
Equation for finding out the Ecliptic Distance, Kranti Vritteya Mandakarna, of a planet
