n. Abbr. cos
1. In a right triangle, the ratio of the length of the side adjacent to an acute angle to the length of the hypotenuse.
2. The abscissa at the endpoint of an arc of a unit circle centered at the origin of a Cartesian coordinate system, the arc being of length x and measured counterclockwise from the point (1, 0) if x is positive or clockwise if x is negative.

Now, gentlemen cosines, will you cease to throw parabolas and hyperbolas at each other's heads?
To control any operation in real-time environment, a number of complex algorithms have to be performed repeatedly which involves use of non-algebraic and arithmetic operations (like addition, multiplication, division, cosine inverse, square roots etc) [1].
Ye [30] developed three vector similarity measure for SNSs, interval valued neutrosophic sets including the Jaccard [31], Dice [32], and cosine similarity measures [33] for SVNS and INSs and applied them to multicriteria decision-making problems with simplified neutrosophic information.
This paper is organized as follow: In section 2 some basic definitions of neutrosophic set, single valued neutrosophic set, interval valued neutrosophic set and cosine similarity measure are presented briefly.
