'Obtain first the result of multiplying the \*jyā\* (of a given \*dhanus\*) by the \*trijyā\* and dividing the product by the \*koṭi\* (of the \*dhanus\*). Multiply this result by the square of the \*jya\* and divide the square by the \*koti\*. Thus we obtain a second result, (as also) a sequence of the further results by repeatedly multiplying by the square of the \*jya\* and dividing by the square of the \*koti\*. Divide the terms of the sequence in order by the odd numbers 1, 3, 5, etc.; after this, add all the odd terms and subtract from them all the even terms (without disturbing the order of the terms). Thus is obtained the \*dhanus\* whose two elements are the given \*jya\* and \*koti\*. Here, the smaller of the two elements should be taken as the \*jya\*, since, otherwise, the series obtained will be non-finite (in value).’
