sine, sin - ratio of the length of the side opposite the given angle to the length of the hypotenuse of a right-angled triangle arc sine, arcsin, arcsine, inverse sine - the inverse function of the sine; the angle that has a sine equal to a given number cos, cosine - ratio of the...
The sine and cosine of a complex argument may assume real values that exceed 1 in absolute value. For example, The trigonometric functions of a complex argument are analytic functions. Furthermore, sin z and cos z are entire functions, and tan z, cot z, sec z, and csc z are meromorphic...

In a right triangle with an angle θ, the cosine function gives the ratio of adjacent side to hypotenuse; more generally, it is the function which assigns to any real number θ the abscissa of the point on the unit circle obtained by moving from (1,0) counterclockwise θ units along the...
Consider a circle centered at the origin with radius one. The segment from the origin to a point P on the unit circle forms an angle x with the positive x-axis. The abscissa of P is the cosine of x. Cosine Definition In terms of a right triangle, thecosineof an acute angle is a ...
One of the interesting properties of the cosine function (and of the trigonometric functions in general) is its periodicity. A functionfis said to be periodic if there exists a real number not equal to zero, say,p, such thatf(x+p)=f(x)for everyxin the domain off. The smallest positive...
Finally, a practical example about the decision-making problems of investment alternatives is presented to demonstrate the effective applications of the proposed MAGDM method under an LNN environment. Keywords: cosine similarity measure; linguistic neutrosophic number; multiple attribute group decision-making...
