Ease of Planetary Calculation

Book/Chapter 6 Tropical Sun = 4 The longitude of the sun adjusted for precession. Desired shadow square = 2 Midday minus the hour angle is the altitude; the wise know that before midday is the eastern hemisphere, and after is the western.

South/North || Half of 30 is subtracted; that doubled is the measure of the whole night.
The fifteen Ghatis A Ghati is a unit of time equal to 24 minutes. are increased or decreased by the ascensional difference. From these two results, half the day is produced. Their sum multiplied by two is 30, which is the night; the results are 15 and 15.

The equinoctial shadow multiplied by five is 5. The square of the equinoctial shadow divided by ten and subtracted from the original is always southern: 5.
The Akshachhaya The shadow of a vertical gnomon at noon on the equinox. is the base. Its square divided by ten, subtracted from the elements, gives the degrees of latitude: 6. The remainder is the hour angle (Nata) for the east or west. From sunrise to the meridian is the [eastern] hemisphere; from there arises the western hemisphere. There, the hour angle and altitude are spoken of in order, just like the Sun.

Midday Equinoctial shadow
Time subtracted from that half-day is the hour angle. 2 digits The square of the equinoctial shadow divided by twelve and added to the sun's position gives the hypotenuse in digits: 9. Result || 2 =

The "Lord of the Vedas" (120) minus the ascensional difference, for North or South. The divisor, which is the Ghatis Ghatis etc. added to it, becomes half the sum. Equal Sun || Equal minus.

The value its own divisor is remembered. || If it is less than 300, the hour angle is subtracted; if more, it is multiplied by four and subtracted. That combined with the divisor is the desired value.

The given hypotenuse is multiplied. || 8 The shadow of the day multiplied by the ascensional difference, multiplied by its own quality, is the pair of ages...

Its own divisor is the dividend. Hypotenuse The hypotenuse in digits and so on is the divisor here. The square root of the difference between the squares of the hypotenuse and the gnomon shall be the desired shadow. 8 The hypotenuse shall be... Now he speaks of the inverse calculation =

Shadow of the gnomon Hypotenuse
The square of the sun's shadow added to the square of the gnomon; the divisor is the sun. The divisor is produced by subtracting the product of the equinoctial shadow. To be done.

Zero 1 15 Earth (1) and 94; taken separately, 94 minus the Vedas (4). The square root of that is the hour angle in Ghatis, subtracted from the half-day: 10.

...just as it is with the parts. To find the root of a fraction, first make the denominator uniform, then divide and take the root. || 7 ||

These are the day-sun values. Having subtracted the movement, doubled... according to the solar authority. Having subtracted the smaller, then from the double-odd, place the double of the root in the row. In the row, the result is the square of the odd... multiplied by two: 1 || 0 || In the remainder, multiply by sixty to get the seconds; with the doubled divisor, the root is found. 2
