# How to use *Cosine* in a sentence

Consequently, one of the forms suitable for the teeth of wheels is the involute of a circle; and the obliquity of the action of such teeth is the angle whose

**cosine**is the ratio of the radius of their base-circle to that of the pitch-circle of the wheel.On examining the diagram it will be observed that the maximum compressive stresses are parallel to and near to the down stream face of the section, which values are approximately equal to the maximum value of the vertical stress determined by the law of uniformly varying stress divided by the

**cosine**squared of the angle between the vertical and the resultant.Further, if polarized light fall at the polarizing angle on a reflecting surface, the intensity of the reflected stream depends upon the azimuth of the plane of incidence, being proportional to the square of the

**cosine**of the angle between this plane and the plane of the polarization.Each grid box was weighted by surface area, using the

**cosine**of the latitude.The inverse

**cosine**is defined only in the domain from ` -1 ' to ` 1 ' .AdvertisementRelative to the number of elements in the detector the discrete

**cosine**proves inefficient, particularly with regard to modulation information.The result is in the range of - pi /2 through pi /2. acos( x) arc

**cosine**of an angle.Note that index 1 is for the higest frequency

**cosine**instead of the 0 frequency sin.Power series, radius of convergence, important examples including exponential, sine and

**cosine**series.The larger OUT cell, also in a

**cosine**corrected mount, is used to measure the illuminance from a whole overcast hemisphere.AdvertisementThe pictures below show the

**cosine**squared distribution of the ejected photoelectron in the presence of multiple scattering.They use sine,

**cosine**and tangent in right-angled triangles when solving problems in two dimensions.Relationships and common formulae from elementary trigonometry, including the basic properties of sine and

**cosine**.He introduced the words

**cosine**and cotangent, and he suggested to Henry Briggs, his friend and colleague, the use of the arithmetical complement (see Brigg's Arithmetica Logarithmica, cap. xv.).In considering the relative brightnesses of the different spectra, it is therefore sufficient to attend merely to the principal directions, provided that the whole deviation be not so great that its

**cosine**differs considerably from unity.AdvertisementAs far as the circlesquaring functions are concerned, it would seem that Gregory was the first (in 1670) to make known the series for the arc in terms of the tangent, the series for the tangent in terms of the arc, and the secant in terms of the arc; and in 1669 Newton showed to Isaac Barrow a little treatise in manuscript containing the series for the arc in terms of the sine, for the sine in terms of the arc, and for the

**cosine**in terms of the arc. These discoveries 1 See Euler, ” Annotationes in locum quendam Cartesii," in Nov.If six films of the same liquid meet in a point the corresponding tetrahedron is a regular tetrahedron, and each film, where it meets the others, has an angle whose

**cosine**is - i.After Rankine, a French engineer, Bouvier, gave the ratio of the maximum stress in a dam to the maximum vertical stress as 1 to the

**cosine**squared of the angle between the vertical and the resultant which, in dams of the usual form, is about as 13 is to 9.
