Surya Siddhanta
तद्गुणे भुजकोटिज्ये भगणाम्शविभाजिते ।तद्भुजज्याफलधनुर् मान्दम् लिप्तादिकम् फलम्॥
Multiply the sines of the Bhuja and Koṭi (of the given 1st and 2nd Kendra of a planet) by the rectified periphery (of the 1st and 2nd epicycle of the planet), and divide the products by the degrees in a circle or 360° (the quotients are called the 1st or 2nd Bhuja-phala and Koṭi-phala respectively). Find the arc whose sine is equal to the 1st Bhuja-phala: the number of the minutes contained in this arc is the manda-phala[1] (or the 1st equation of the planet.)
