Unit circle — In mathematics, a unit circle is a circle with a unit radius, i.e., a circle whose radius is 1. Frequently, especially in trigonometry, the unit circle is the circle of radius 1 centered at the origin (0, 0) in the Cartesian coordinate system in… … Wikipedia
Trigonometric interpolation — In mathematics, trigonometric interpolation is interpolation with trigonometric polynomials. Interpolation is the process of finding a function which goes through some given data points. For trigonometric interpolation, this function has to be a… … Wikipedia
Trigonometric polynomial — In the mathematical subfields of numerical analysis and mathematical analysis, a trigonometric polynomial is a finite linear combination of functions sin(nx) and cos(nx) with n a natural number. The coefficients may be taken as real numbers, for… … Wikipedia
Trigonometric moment problem — In mathematics, the trigonometric moment problem is formulated as follows: given a finite sequence { α 0, ... αn }, does there exist a positive Borel measure mu; on the interval [0, 2 pi; ] such that:alpha k = frac{1}{2 pi}int 0 ^{2 pi} e^{… … Wikipedia
Trigonometric rational function — In mathematics, a trigonometric rational function is a rational function in the functions sin theta; and cos theta;. Equivalently, it is a ratio of trigonometric polynomials. The simplest examples (besides sin theta; and cos theta; themselves)… … Wikipedia
