Reflectance is a component of the response of the electronic structure of the material to the electromagnetic field of light, and is in general a function of the frequency, or wavelength, of the light, its polarization, and the angle of incidence.
To reproduce color, the CMYK color model codes for absorbing light rather than emitting it (as is assumed by RGB). The "K" component absorbs all wavelengths and is therefore achromatic. The cyan, magenta, and yellow components are used for color reproduction and they may be viewed as the inverse of RGB.
When working with right triangles, sine, cosine, and other trigonometric functions only make sense for angle measures more than zero and less than π / 2 . However, when defined with the unit circle, these functions produce meaningful values for any real-valued angle measure – even those greater than 2 π.

A table comparing four different scales for the hydrophobicity of an amino acid residue in a protein with the most hydrophobic amino acids on the top. A number of different hydrophobicity scales have been developed. [3] [1] [7] [8] [9] There are clear differences between the four scales shown in the table. [10]
Those with Cobb angle of more than 60° usually have respiratory complications. [7]Scoliosis cases with Cobb angles between 40 and 50 degrees at skeletal maturity progress at an average of 10 to 15 degrees during a normal lifetime.
The Telecommunications Industry Association's TIA-598-C Optical Fiber Cable Color Coding is an American National Standard that provides all necessary information for color-coding optical fiber cables in a uniform manner.
The trigonometric functions of angles that are multiples of 15°, 18°, or 22.5° have simple algebraic values. These values are listed in the following table for angles from 0° to 45°. [1] In the table below, the label "Undefined" represents a ratio :
