cosine, tangent, cotangent, secant and cosecant. these formulas are used to solve various trigonometry problems. in mathematics, trigonometry is one of the most important topics to learn. trigonometry is basically the study of triangles where ‘trigon’ means triangle and ‘metry’ means measurement...

And in case we have only one singularity, as indeed follows from one of the theorems of Yang and Lee (1952), it must exist at a temperature Tc such that Tc*=Tc. The critical temperature of the square lattice is, therefore, given by the equation, see formula (12), (18)sinh(2Kc)=...
There is a nice duality of theorems if you define a Point in this new geometry as a pair of antipodal points on a sphere, and a Line as a great circle on a sphere. Thus two distinct Lines uniquely determine a Point, and two distinct Points uniquely determine a line. This is a bit ...
Let \overline{G} be the complement of G. Since \alpha (G)=2, \overline{G} has no triangles. It is well-known that the complement of an odd cycle C_n with n\ge 5 has at least three positive eigenvalues. Therefore, by interlacing, \overline{G} has no induced odd cycle, so \over...
1.7. The structure rif this paper Theorems 1,:1 and 1.4 are proved in the next section. Our proofs combines combinatorial reasonings with applying certain inequalities for the Fourier codflCients of Bonami and Beckner which were used already in [23]. However, to get the resulrs in the ...
