As a continuation of An and Yang (Integral Equ Oper Theory 66:183-195, 2010) in this paper, The symmetrized Sine addition formula w ( xy ) + w ( yx ) = 2 f ( x ) w ( y ) + 2 w ( x ) f ( y ) is studied, where f, w are the unknown complex functions on a group ...
Question: Use addition formulas to derive the identity:sin(x−π2)=−cosx Additional Formulas: The six additional formulas of trigonometry that help us in the solution of several trigonometric problems are given below: sin(a±b)=sin(a)cos(b)±cos(a)sin...
These four identities are sometimes called the sum identity for sine, the difference identity for sine, the sum identity for cosine, and the difference identity for cosine, respectively. The verification of these four identities follows from the basic identities and the distance formula between points...

As a result, it has been proved by the formula that the activation energy of the η phase is decreased, and the activation entropy is increased. Therefore, the η phase growth is suppressed. Both the previous studies and this work indicate that the solid solution of Si in the η phase ...
