YOu can get a flower-like shape by putting it in polar mode and using the equation r = a cos nθ where a and n are whole numbers. We establish long-time existence results for quasilinear wave equations in the exterior of star-shaped obstacles. Controlabilite approchee des equations d'ondes Id couplees surgraphes etoiles Rene Dager ABSTRACT In this Note, we study the approximate controllability of a cascade system of two 1-d wave equations defined on a star-shaped planar graph. Water wave propagation in an open channel network can be described by the viscous Burgers' equation on the corresponding connected graph, possibly with small viscosity. The first are used in definitions of star polyhedra and star uniform tilings, while the second are sometimes used in planar tilings. temperature layer by layer toward the center of a star, you find the Thus we can find the area of this shape and multiply by five to find the area of the star. We prove global existence of small-amplitude solutions of quasilinear Dirichlet-wave equations outside of star-shaped obstacles in (3 + 1)-dimensions. hydrostatic equilibrium. By using the moment theory we can derive null-controllability properties with boundary controls acting on the external vertices of the tree. Cartesian equation of star shape. using this technique you can draw a whole bunch of stars. The problem of small vibrations of a graph consisting of n smooth inhomogeneous stretched strings joined at the vertex with the pendant ends fixed is reduced to the Sturm–Liouville boundary problem on a star‐shaped graph. More precisely, the equation is considered on a star-shaped tree with Dirichlet and Neumann boundary conditions. Where will the planet be in its orbit at some later time t?.
