Sin Function

sin x = 16x (p - x)/[5p2- 4x (p - x)]

x = 0 formula = 0.00000 sin x = 0.00000 error = 0.00000

x = p/20 formula = 0.15800 sin x = 0.15643 error = 0.00157

x = p/10 formula = 0.31034 sin x = 0.30903 error = 0.00131

x = 3p/20 formula = 0.45434 sin x = 0.45399 error = 0.00035

x = p/5 formula = 0.58716 sin x = 0.58778 error = -0.00062

x = p/4 formula = 0.70588 sin x = 0.70710 error = -0.00122

x = p/10 formula = 0.80769 sin x = 0.80903 error = -0.00134

x = 7p/20 formula = 0.88998 sin x = 0.89103 error = -0.00105

x = 2p/5 formula = 0.95050 sin x = 0.95105 error = -0.00055

x = 9p/20 formula = 0.98753 sin x = 0.98769 error = -0.00016

x = p/2 formula = 1.00000 sin x = 1.00000 error = 0.00000


If found that on the internet and it is pretty accurate.. there are some stuff with approximation series but i couldnt get it to work right, but this seems to work very well. The formula which is amazingly accurate and use of the formula leads to a maximum error of less than one percent

And PS this formula was first discovered by this indian guy named Bhaskara I in 629 AD.

Now all u got to do is find a formula for Cos and ur set lol
