Math.abs(n):Returns the absolute value of n. Math.acos(n):Returns the inverse cosine (in radians) of n. Math.asin(n):Returns the inverse sine (in radians) of n. Math.atan(n):Returns the inverse tangent (arctangent) of n, a value in the range -PI/2through PI/2. Math.atan2(...
Data are recorded during the second heating, and an extension line from the base-line prior to the initial rise of the first endothermic peak and a tangent line exhibiting the maximum slope between the initial rise and the peak are drawn and the intersection of both lines is defined as the...
3. The fixing device according to claim 2, wherein an end of the reflecting member located near to the support member is located closer to the support member than a tangent to part of the curved portion of the support member located nearest to the laser source. 4. The fixing device accor...
atan2(y, x):Calculates the inverse tangent of y/x and returns an angle in the range -PIto PI, using the signs of the arguments to determine the quadrant. Multiply theresult by 180/PI to convert to degrees. cos(angle):Returns the cosine of an angle (in radians). ...
find two points on the tangent which is not the part of the lip. For the lower lip, we find two point similar process of the upper lip. We use Cubic Bezier curves for draw the Bezier curve of the lip. We draw two Bezier curve for the lip, one for upper lip and one for lower ...
Nevertheless it has to be noticed that a linear relationship between the retardation and the phase values obtained by applying the arctangent functions to the intensity levels of the R, G and B components can be obtained [16,18,70,72], depending on the spectral properties of the filters of...

The chord inclination angle feature used in the initial screening of segmentation points utilizes the jagged contour, thus eliminating the need for the smoothing of the contour, avoiding errors caused by smoothing and at the same time being sensitive enough to tangent points and inflection points. ...
