The grease pencil, a wax writing tool also known as a wax pencil, china marker, or chinagraph pencil (especially in the United Kingdom), is a writing implement made of hardened colored wax and is useful for marking on hard, glossy non-porous surfaces.
Using a black Royal Sovereign Chinagraph pencil I am exploring methods of blending, spreading, removing and fixing the black marks on paper, for artwork sketching and drawing. The black marks can be removed easily by washing in cold soapy water. That is not what would be expected from a wax, but is typical of an oil or grease I believe.
Each curve in the pencil passes through the nine points of the complex projective plane whose homogeneous coordinates are some permutation of 0, –1, and a cube root of unity. There are three roots of unity, and six permutations per root, giving 18 choices for the homogeneous coordinates of each point, but they are equivalent in pairs giving ...
The Geometry Nodes utility also has the capability of creating primitive meshes. [36] In Blender 3.0, support for creating and modifying curves objects was added to Geometry Nodes; [37] in the same release, the Geometry Nodes workflow was completely redesigned with fields, in order to make the system more intuitive and work like shader nodes ...
The Marshall-Edgeworth index, credited to Marshall (1887) and Edgeworth (1925), [11] is a weighted relative of current period to base period sets of prices. This index uses the arithmetic average of the current and based period quantities for weighting.
A kink in an otherwise linear demand curve. Note how marginal costs can fluctuate between MC1 and MC3 without the equilibrium quantity or price changing. The Kinked-Demand curve theory is an economic theory regarding oligopoly and monopolistic competition. Kinked demand was an initial attempt to explain sticky prices.
A crunode at the origin of the curve defined by (+) =. In mathematics, a crunode [1] (archaic; from Latin crux "cross" + node [2]) or node of an algebraic curve is a type of singular point at which the curve intersects itself so that both branches of the curve have distinct tangent lines at the point of intersection.
The definitions for plane curves and implicitly-defined curves have been generalized by René Thom and Vladimir Arnold to curves defined by differentiable functions: a curve has a cusp at a point if there is a diffeomorphism of a neighborhood of the point in the ambient space, which maps the curve onto one of the above-defined cusps.
