Aryabhatiya is a Sanskrit treatise written by Aryabhata in 499 CE. It is considered to be one of the most important works in the history of Indian mathematics.

Aryabhata approximated the value of pi to be 3.1416, which is accurate to four decimal places.

Kuttaka is a method developed by Aryabhata for solving indeterminate linear equations. It is a recursive method that involves finding a particular solution to the equation and then using that solution to find other solutions.

The Pythagorean Theorem is a theorem that states that the sum of the squares of the two sides of a right triangle is equal to the square of the hypotenuse. It is one of the most famous theorems in mathematics.

Aryabhata's Formula is a method for finding the area of a triangle. It states that the area of a triangle is equal to half the product of its base and height.

Aryabhata's Method is a method for finding the volume of a sphere. It states that the volume of a sphere is equal to the product of its radius and the circumference of a great circle.

Aryabhata's Method is a method for finding the circumference of a circle. It states that the circumference of a circle is equal to the product of its diameter and the square root of 10.

Aryabhata's Method is a method for finding the sine of an angle. It states that the sine of an angle is equal to the ratio of the length of the opposite side to the length of the hypotenuse.

Aryabhata's Method is a method for finding the cosine of an angle. It states that the cosine of an angle is equal to the ratio of the length of the adjacent side to the length of the hypotenuse.

Aryabhata's Method is a method for finding the tangent of an angle. It states that the tangent of an angle is equal to the ratio of the length of the opposite side to the length of the adjacent side.

Aryabhata's Method is a method for finding the cotangent of an angle. It states that the cotangent of an angle is equal to the ratio of the length of the adjacent side to the length of the opposite side.

Aryabhata's Method is a method for finding the secant of an angle. It states that the secant of an angle is equal to the ratio of the length of the hypotenuse to the length of the adjacent side.

Aryabhata's Method is a method for finding the cosecant of an angle. It states that the cosecant of an angle is equal to the ratio of the length of the hypotenuse to the length of the opposite side.

Aryabhata's Method is a method for finding the inverse sine of an angle. It states that the inverse sine of an angle is equal to the angle whose sine is equal to the given angle.

Aryabhata's Method is a method for finding the inverse cosine of an angle. It states that the inverse cosine of an angle is equal to the angle whose cosine is equal to the given angle.
