Indian Mathematicians in Geometry

Brahmagupta is known for his work on the Brahmagupta theorem, which states that in a cyclic quadrilateral, the sum of the products of the opposite sides is equal to the product of the diagonals.

Aryabhata is credited with developing the concept of the sine function. He also developed a table of sines, which was used for astronomical calculations.

Aryabhata is credited with developing the concept of the cosine function. He also developed a table of cosines, which was used for astronomical calculations.

Brahmagupta is known for his work on the Pythagorean theorem. He provided a geometric proof of the Pythagorean theorem and also developed a formula for calculating the hypotenuse of a right triangle.

Aryabhata is credited with developing the concept of the tangent function. He also developed a table of tangents, which was used for astronomical calculations.

Brahmagupta is known for his work on the area of a triangle. He developed a formula for calculating the area of a triangle using its sides.

Brahmagupta is known for his work on the volume of a sphere. He developed a formula for calculating the volume of a sphere using its radius.

Aryabhata is credited with developing the concept of the secant function. He also developed a table of secants, which was used for astronomical calculations.
