Figura ilustrează nivelul de precizie al formulei de aproximare a sinusului Bhaskara I. Curbele deplasate 4 x(180 - x) / (40500 - x(180 - x)) - 0,2 și sin ( x) + 0,2 arată ca copii exacte ale curbei sin ( x). In the seventh century adthe Indian mathematician Bhāskarā I gave a curious rational approximation to the sine function; he stated that if 0 ≤ x≤ 180 then sin xdeg is approximately equal to 4x(180 - x)/(40500 - x(180 - x)). He also gave the following approximation formula for sin(x), . An Indian mathematician, Bhaskara I, gave the following amazing approximation of the sine (I checked the graph and some values, and the approximation is truly impressive.) Bhaskara I's sine approximation formula. Just thought I'd share. The series is infinite and the more terms you include the closer to the true value you will get. The sine function was later also adapted in the variant jīv . I now need the inverse of this formula in order to approximate the inverse sine. sin x ≈ 16 x ( π − x) 5 π 2 − 4 x ( π − x) for ( 0, π) Here's an image. Grover [1] provides a possible explanation, but I think the rule can be explained more clearly. Find something interesting to watch in seconds. MONT 109N -- Bhaskara's Approximation of the sine April 11, 2011 In the text known as the Maha Bhaskariya (c. 600 CE), the classical-period Indian mathematician Bhaskara developed the following approximation to the sine function (given for an angle in degrees, with the radius of the circle set to (I'd figure out how to "crop" it once I can visualise it in Desmos.) The below is some glsl code from @paniq that has been adapted to take 0 to 1 as input, which corresponds to 0 to 2*pi radians, or 0 to 360 degrees, and returns the normalized vector of that angle. In general you pick a value of the function about which you want to approximate via Taylor series. A little something I "discovered" by playing around with Bhaskara's sine approximation.

There is an even simpler argument to obtain Bhaskara's formula. According to his formula: Bhaskara i knew the approximation to the sine functions that yields close to 99% accuracy, using a function that is simply a ratio of two quadratic functions. The series is infinite and the more terms you include the closer to the true value you will get. Grover [1] provides a possible explanation, but I think the rule can be explained more clearly. These form a polynomial which represents an ever-improving approximation to a function. In general you pick a value of the function about which you want to approximate via Taylor series.

Summary. This gives Bhaskara's approximation formula for the sine function. Compare the approximated values to the exact values for the following functions and briefly explain your results. Hopefully, this might come in handy for some mapmakers or data pack writers out there. In the seventh century AD the Indian mathematician Bhaskara I gave a curious rational approximation to the sine function; he stated that if 0 &le x ≤ 180 then sin x deg is approximately equal to 4x. + x^5 / 5!. Cookie-policy He was the one who came up with the formula for computing the areas of triangles and circles. Bhāskara (c. 600 - c. 680) (commonly called Bhaskara I to avoid confusion with the 12th-century mathematician Bhāskara II) was a 7th-century mathematician and astronomer, who was the first to write numbers in the Hindu decimal system with a circle for the zero, and who gave a unique and remarkable rational approximation of the sine function in his commentary on Aryabhata's work. Bhaskara I's sine approximation formula. In mathematics, a Padé approximant is the "best" approximation of a function by a rational function of given order - under this technique, the approximant's power series agrees with the power series of the function it is approximating. The technique was developed around 1890 by Henri Padé, but goes back to Georg Frobenius, who introduced the idea and investigated the features of rational . In this particular case, we have f(x) = x + sin(x), and, as sin(n*pi) = 0 for any integer n, any multiple of pi is a solution of that equation. This formula is given in his treatise titled Mahabhaskariya. Bhaskara I's sine approximation formula: Which is India's second artificial satellite?
