However, our algorithm uses the triangular relation between the three directional cosine to resolve the ambiguity.

The spherical law of cosines (5) with the help of the simplified Hardy approximation (14) enables to calculate the approximate value of the sphere radius in cases of a tiny curvature where Pythagoras' theorem approximately rules.
Less frequently seen is the Law of Cosines, which permits calculation of the length of all sides and magnitude of all angles in a triangle, if the length of two sides and magnitude of the angle between them are known.
Given a semantic space, the cosines of P should be calculated with each of the terms that make up the semantic space.
Similar verifications can be done for SAS and ASA using the laws of sines and cosines. We encourage the reader to try some of these.
Now [L.sub.1], [M.sub.1], [N.sub.1] and [L.sub.2], [M.sub.2], [N.sub.2] are the direction cosines of object PQ and RS respectively and T1T2 is the shortest distance.
The condition of 100% collection of protons is very important as the average cosines for the a and B correlation coefficients will be equal to zero in this case.
Two instructors at Anoka Ramsey Community College progress through functions and graphs, polynomial and rational functions, logarithmic functions, trigonometric functions, sines and cosines, systems of equations and inequalities, sequences, and probability with a final chapter on analytic geometry.
With clues and in-class preparation, I have found this to be a generally accessible homework problem for students, leading them to their own discovery of the Law of Cosines. Through examples, one can then help students realize that coordinates can be a convenient addition to the context.
At the higher end, the range of LSA cosines ran from strong impact (.86), to medium impact (.72) and to weak coherence (.63).
Then, from the spherical triangle between N, V and R, using the law of cosines for sides, we find the angle between the transmitter's velocity vector and the receiver:
Developed in the early 1800s by Joseph Fourier, Fourier transforms are approximations using the super: position of sines and cosines to represent other functions.
This states that any periodic oscillation (that is, any variation that sooner or later repeats itself exactly, over and over) can be broken up into a series of simple regular wave motions (expressed as sines and cosines), the sum of which will be the original complex periodic variation.
