trigonometry is a branch that deals with the study of angles and sides of a right triangle. based on the sides and the angles, the trigonometric functions can be classified into six types, namely sine, cosine, tangent, cosecant, secant and cotangent. the trigonometric ratios of these six fun...
All of the approximations here are polynomials, or ratios of polynomials. All use very cryptic coefficients derived from Chebyshev series and Bessel functions. Rest assured that these numbers give minimum errors for the indicated ranges. Each approximation (with a few exceptions) has an error chart ...
