Unit Circle Triangles The idea of sine and cosine can be applied for every real number, and not only for the angles of a right triangle. The notion of a tangent, however, cannot be extended to some numbers because it is the ratio between the sine and the cosine. Because it is a fract...
Given a nontrivial positive measure $\\\mu$ on the unit circle, the associated Christoffel-Darboux kernels are $K_n(z, w;\\\mu) = \\\sum_{k=0}^{n}\\\overline{\\\varphi_{k}(w;\\\mu)}\\\,\\\varphi_{k}(z;\\\mu)$, $n \\\geq 0$, where $\\\varphi_{k}(\\\...
