Amongst the lay public of non mathematicians and non scientists, trigonometry is known chiefly for its application to measurement problems, yet is also often used in ways that are far more subtle, such as its place in the music theory theory of music still other uses are more technical, such as in number theory . The mathematical topics of Fourier series and Fourier transforms rely heavily on knowledge of trigonometric functions and find application in a number of areas, including statistics . Some fields in which trigonometry is applied Among the scientific fields that make use of trigonometry are these acoustics , architecture , astronomy and hence navigation , on the oceans, in aircraft, and in space in this connection, see Great circle distance great circle distance , biology , cartography , chemistry , civil engineering , computer graphics , geophysics , crystallography , economics in particular ... perception , education .

Expert subject Mathematics date November 2008 In mathematics , trigonometry analogies are supported by the theory of quadratic extension s of finite field s, also known as Galois fields. The main motivation to deal with a finite field trigonometry is the power of the discrete transform s, which play an important role in engineering and mathematics. Significant examples are the well known discrete trigonometric transforms DTT , namely the discrete cosine transform and discrete sine transform , which have found many applications in the fields of digital signal and image processing . In the real DTTs, inevitably, rounding is necessary, because the elements of its transformation matrices are derived from the calculation of sines and cosines. This is the main motivation to define the cosine transform over prime finite fields . In this case, all the calculation is done using integer arithmetic. In order to construct a finite field transform that holds some resemblance with a DTT or with a discrete transform that uses trigonometric function s as its kernel, like the discrete Hartley transform , it is firstly necessary to establish the equivalent of the cosine and sine functions over a finite structure. Trigonometry over a Galois field The set GI q of gaussian integer s over GF q plays an important role in the trigonometry over finite fields hereafter the symbol denotes equal by definition .
