Delight of Mathematicians (1912) - Page 18

original: "Graha Karanjani"

Verse: ...is joined. From the distance traveled in a day, subtract the seconds of arc after dividing by eighteen. In the era of thirty-six hundred 3600 years of the Kali Yuga, take the remainder, multiply by eighteen and divide; when these minutes are added to the position, it becomes the Mean Mars Madhya Kuja.

Explanation: Divide the doubled value by 2 and keep it in two places. If you divide the first part by 40, you get the minutes of arc; if you divide the second part by 20, you get the degrees. If you divide [the original value] by 8 and add it to the doubled value, it becomes the position of Mars Kuja. Add the epoch constant Dhruva the fixed starting position of 0-12-20-46. Multiply the years of the era Karanabda by 3 and divide by 5360; add the resulting degrees. From the mean motion Madhya Gati, multiply by 20 and divide by 80, then subtract the resulting seconds of arc.

Subtract 3600 from the elapsed years of the Kali Yuga Kalyadigata, multiply by 18 and divide by 15. If you add the resulting minutes, it becomes the Mean Mars corrected for observation Drik-Samskara Madhya Kuja.

Calculation for Mercury

original: "Budha Sadhanam"

Verse: The double amount multiplied by four gives the degrees. From the double amount, multiply by six and divide by sixty-one. To this, add the constant 7-1-12-44. For the years of the era, multiply by three and divide by seven hundred and eighty-eight 788 to find the degrees to be added for Mercury Budha. From the daily motion, divide the seconds by eight and subtract.

Explanation: Multiply the doubled value by 4 to get the degrees. Multiply the doubled value by 6 and divide by 61 to get the degrees. Add these together to find Mercury Budha. Add the epoch constant Dhruva of 7-1-12-44. Multiply the tripled years of the era Trigunabda and divide by 788; add the resulting degrees and perform the motion correction Gati Samskara.

Calculation for Jupiter

original: "Guru Sadhanam"

Verse: The double amount multiplied by five [results in] the minutes of arc for Jupiter Guru. From the double amount, subtract the seconds of arc divided by seventy (70). For Jupiter, five, eight, six, one, zero... The verse cuts off as it lists the constant or divisor
