Some Approximations for Trigonometrical Functions
1980It is shown that better approximations of tan(x) are obtained if the singular part is taken out, i.e. if we write tan(x) = S(x) + R(x) where S contains the singular part of tan in the sense that the rest R(x) is finite for x → one or several of the points ±π/2,±3π/2,...

Some Notes on Trigonometric Approximation
2011Let us denote by (c[a, b] c[0, 2p]) the space of all real continuous (2p-periodic) functions f provided with the uniform norm \({\parallel{f}\parallel} = {\mathop{\sup}\limits_{x\in[a,b]}}\,|\,f(x)\,|\,\,\,{\left(=\,\,{\mathop{\sup}\limits_{x\in[a,b]}}\,|\,f(x)\,|\right)}.\)

APPROXIMATE POLYNOMIALS OF TRIGONOMETRICAL SERIES
Survey Review, 1973AbstractApproximate polynomials of the arctangent, tangent, cosine and sine series are offered which are suitable for use on small desk-top programmable computers, or on pocket computers in the field, which do not have inbuilt facilities for evaluating trigonometrical functions.
