By applying the logarithm function, the parts where the defining function is negative are not shown in the 3D plot, as they give rise to complex-valued function values. WebI. Yu.

WebWe present a Rvachev function method with the Chebysev collocation for the stability analysis of fluid flow. The strategy is to construct an approximate solution that satisfies all boundary conditions exactly. As an example, we consider the stability problem of the two-dimensional flow of an incompressible viscous liquid near a circular cylinder. cyprus holidays coral bay

WebMay 1, 2016 · The Fabius function assumes rational values at dyadic rational arguments. We will give an explicit formula for those values. Because dyadic rationals form a dense subset of the reals, and the Fabius function is continuous, its value at any real point can be found as a limit of its values on a sequence of dyadic rationals converging to that point. http://blog.wolfram.com/2013/08/15/even-more-formulas-for-everything-from-filled-algebraic-curves-to-the-twitter-bird-the-american-flag-chocolate-easter-bunnies-and-the-superman-solid/
