In this paper, we have defined rough neutrosophic hyper-complex set and rough neutrosophic hyper-complex

cosine function (RNHCF).

In order to overcome theses disadvantages, Ye [53] proposed improved cosine similarity measures based on

cosine function, including single valued neutrosophic cosine similarity measures and interval neutrosophic cosine similarity measures.

Overplotted is a

cosine function, cos ($4n), (see fig.

Fourier theory is that a signal can be used for a series of the

cosine function is cumulative and representation, but Fourier transform only the frequency resolution without time resolution.

If we compare this function to the

Cosine function of the traditional trigonometry we find that the Elliptic Jes function is the general case of the

cosine function and it is defined as following:

This can lead students to think that the angle is not important and that the angle for the sine function and the angle for the

cosine function need not agree for the identity to be true.

At the end of each rule statement, the rule was recited by all participants in unison: "When multiplying the

cosine function by a number greater than 1, the graph stretches along the y axis.

Errors are a function of angle and have maximum magnitude near the zeros of the

cosine function.

The angle of arrival referenced to the centre point of one sensor pair can be calculated using the inverse

cosine function (Arcus-Cosine) (Fig.

In this experiment students investigate the graph of the

cosine function by measuring the thrust force as a function of the angle.

The diurnal variation of vertical ionospheric delay is modelled by a

cosine function, with varying amplitude and period, depending on the geomagnetic latitude.

Figure 5 shows the

cosine function compared to three commercial radiometers and FWT-60 radiachromic ("radiachromic") film.
