Ease of Planetary Calculation

Note 7. The noble teacher original: "Arya" explains the method for calculating declination original: "Kranti-sadhana" = 1

Midday 15 ghatis Difference In minutes of time 115 Equinoctial shadow Degrees of solar declination
The difference between the half-day and the lunar day Tithi is the sine of that day reading uncertain?. From one's own position, the shadow is calculated; the degrees of the sun's declination are then determined.

This means that for a midday of fifteen ghatis, the northern declination should be subtracted = 2

... 25 ... these are combined with the midday values. In order, these are South and North: 16. The declination Degrees of altitude when processed results in the degrees of zenith distance original: "Natansha". Addition if in the same direction, subtraction if in different directions = 2

He explains the operation for the direction of altitude = 4 From the two altitudes = 3

Ninety 90 minus that zenith distance results in the degrees of altitude original: "Unnatansha". These arise from the middle of the day Produced at midday. From those, the degrees of declination are found using the small table of sines original: "Laghukhanda". Divided by the degrees of altitude, etc. Declination produced from the small sine table = 4

7 multiplied by ninety 90, then the desired The desired time, etc. altitude is divided by the half-day. From the resulting degrees, the declination is stated...

The hypotenuse is formed by the square of the sun's shadow added to the square of the gnomon declination-multipliers, etc. = 5

By the measure of the day Altitude from the hypotenuse
Six hundred ninety-nine 699 reading uncertain? or it may be 18. The sun's value multiplied by 699 and divided by the maximum value gives the declination.

Then subtract from the half-day, according to this rule = 6

Declination
The zenith distance: the side multiplied by the half-day and divided by ninety 90. Or first, the altitude 19 the zenith distance is the result of the declination process Degrees of zenith distance: 114

The degrees are at the center ... divided by 6, each multiplied by itself and added. Then, the 24 degrees of maximum declination are subtracted from the total...

He explains the zenith distance from the parts of the instrument in reverse order = 1

Degrees of zenith distance, etc., here
20. The half-day 10 20 combined with the zenith distance, multiplied by fifteen 15, and divided by the midday 6... multiplied by the maximum and divided by 16.

Divided, combined with the "Elephant-form" number 248, multiplied by two, then the 6... these are the degrees of zenith distance original: "Natansha".

21. The divisor for the degrees of zenith distance is multiplied by 6. The result is squared, doubled, and added to the "Elephant-form" 248... 24.
