One triangle has angles measuring A, β−α and 90. The other triangle has angles measuring B, α− β, and 90. The two right angles are placed back to back with the two triangles having the same height. Using algebra and substitution, we got something that is similar to the proof but a couple of variables are switched, meaning that there is more work to do. I wonder if this method can be used though...

Because the B d → J/ψK S asymmetry determines only sin 2β, a discrete ambiguity in the true value of β remains. This note reviews how the ambiguity can be removed. Extractions of the CKM angle α are discussed next. Some of the methods require very large data samples and will not be feasible in the near future. In the near future, semi-inclusive CP-violating searches could be undertaken, which a...

UNLABELLED The main method for the early screening of the developmental dysplasia of the hip (DDH) is the ultrasound imaging. There are several studies about the ultrasound imaging of newborns' hips, but only a few studies include the prenatal period of life. Our aim was to examine the prenatal development of the hip joint through the evolution of the α angle seen on the ultrasound, described i...

OBJECTIVE To assess, using transperineal ultrasonography (TPUS), the numerical value of the rotation of the bladder neck [represented by the difference in the anterior (α angle) and posterior urethral angles (β angle)] at rest and straining, in continent women and women with stress urinary incontinence (SUI), to ascertain if there are significant differences in the angles of rotation (Rα and Rβ...

1 Trigonometric Functions We recall the following identities for trigonometric functions. Theorem 1.1. For all x ∈ R, cos(−x) = cos(x) and sin(−x) = − sin(x). Theorem 1.2. For all α, β ∈ R, cos(α + β) = cos(α) cos(β)− sin(α) sin(β). Theorem 1.3. For all α, β ∈ R, sin(α+ β) = sin(α) cos(β) + cos(α) sin(β). Proof. For small positive angles (so α+ β is less than a right angle), the identities from...
