The correct answer is option A) concept of sine angle.
The Surya Siddhanta is an ancient Indian astronomical treatise that was composed in the early fifth and sixth century AD. It is one of the earliest works on Indian astronomy and has had a significant influence on the field. The Surya Siddhanta covers a wide range of topics related to astronomy, including the concept of sine angle.
- Introduction to the Surya Siddhanta:
The Surya Siddhanta is believed to have been written by ancient Indian astronomers and mathematicians. It is named after Surya, the Hindu Sun god, and Siddhanta, which means "treatise" or "principles". The text consists of several chapters that provide detailed explanations and calculations related to various astronomical phenomena.
- Importance of the Sine Angle:
The concept of the sine angle is a fundamental concept in trigonometry and mathematics. It is a ratio that relates the length of the side opposite an angle in a right triangle to the length of the hypotenuse. The sine angle is crucial for calculating distances, heights, and angles in various fields, including astronomy.
- Role of Sine Angle in Astronomy:
In astronomy, the concept of the sine angle is used extensively in calculations related to celestial objects. It helps determine the position, distance, and motion of celestial bodies, including the Sun, Moon, planets, and stars. By using the sine angle, astronomers can calculate the apparent size of objects in the sky, their positions at different times, and the angles at which they rise and set.
- Contribution of the Surya Siddhanta:
The Surya Siddhanta played a significant role in advancing the understanding and application of the sine angle in Indian astronomy. It provided detailed formulas and calculations for various astronomical phenomena, including the measurement of angles. The text presented the concept of the sine angle and its calculations in a systematic and mathematical manner, making it easier for astronomers to make accurate observations and predictions.
In conclusion, the Surya Siddhanta, composed in the early fifth and sixth century AD, was an influential work that dealt with various aspects of astronomy. One of its significant contributions was the introduction and explanation of the concept of the sine angle, which has had a profound impact on the field of astronomy and mathematics.

- Some of the early and very significant developments of trigonometry were in India. Influential works from the fourth and fifth century, known as the Siddhanta's (of which there were five, the most important of which is the Surya Siddhanta), first defined the sine as the modem relationship between half an angle and half a chord, while also defining the cosine, versine, and inverse sine.
- Soon afterwards, another Indian mathematician and astronomer, Aiyabhatta (476-550 AD), collected and expanded upon the developments of the Siddhantas in an important work called the Aryabhatiya.
