[clarification needed] He does this by explaining the illumination of the Moon by the Sun. 1. If the moon were above the sun, how would the power of waxing and waning, etc., be produced from calculation of the longitude of the moon? The near half would always be bright. 2.

- diffhist Brahmagupta 14:00 −1,208 103.190.8.224 talk (After giving the value of pi, he deals with the geometry of plane figures and solids, such as finding volumes and surface areas (or empty spaces dug out of solids). He finds the volume of rectangular prisms, pyramids, and the frustum of a square pyramid. He further finds the average depth of a series of pits. For the volume of a frustum of a pyramid, he gives the "pragmatic" value as the depth times the square of the mean of the edges of the top and bottom faces, and he gives the "superficial" v) Tags: Reverted Visual edit Mobile edit Mobile web edit

The square-root of the sum of the two products of the sides and opposite sides of a non-unequal quadrilateral is the diagonal. The square of the diagonal is diminished by the square of half the sum of the base and the top; the square-root is the perpendicular [altitudes]. So, in a "non-unequal" cyclic quadrilateral (that is, an isosceles trapezoid), the length of each diagonal is √pr + qs.

The accurate [area] is the square root from the product of the halves of the sums of the sides diminished by [each] side of the quadrilateral. So given the lengths p, q, r and s of a cyclic quadrilateral, the approximate area is p + r/2 · q + s/2 while, letting t = p + q + r + s/2, the exact area is √(t − p)(t − q)(t − r)(t − s).

Brahmagupta was not able to apply his solution uniformly for all possible values of N, rather he was only able to show that if x2 − Ny2 = k has an integer solution for k = ±1, ±2) Tags: Reverted references removed Visual edit Mobile edit Mobile web edit
