Web2D Rotation about a point. Rotating about a point in 2-dimensional space. Maths Geometry rotation transformation. Imagine a point located at (x,y). If you wanted to rotate that point around the origin, the coordinates of the new point would be located at (x',y'). x ′ = x cos θ − y sin θ y ′ = y cos θ + x sin θ. Where θ is the angle ...

Introduction. Let k be an algebraically closed field of any char-acteristic, and X be a proper normal surface over k. Let Aut(X/k) be the set of all automorphisms of X over k. … Not all functions have fixed points: for example, f(x) = x + 1, has no fixed points, since x is never equal to x + 1 for any real number. In graphical terms, a fixed point x means the point ( x , f ( x )) is on the line y = x , or in other words the graph of f has a point in common with that line. See more A fixed point (sometimes shortened to fixpoint, also known as an invariant point) is a value that does not change under a given transformation. Specifically, in mathematics, a fixed point of a function is an element that is … See more In algebra, for a group G acting on a set X with a group action $${\displaystyle \cdot }$$, x in X is said to be a fixed point of g if $${\displaystyle g\cdot x=x}$$. The fixed-point subgroup $${\displaystyle G^{f}}$$ of an automorphism f of a group G is the See more In combinatory logic for computer science, a fixed-point combinator is a higher-order function $${\displaystyle {\textsf {fix}}}$$ that returns a fixed point of its argument function, if one exists. Formally, if the function f has one or more fixed points, then See more A fixed-point theorem is a result saying that at least one fixed point exists, under some general condition. Some authors claim that results of … See more A topological space $${\displaystyle X}$$ is said to have the fixed point property (FPP) if for any continuous function $${\displaystyle f\colon X\to X}$$ there exists See more In domain theory, the notion and terminology of fixed points is generalized to a partial order. Let ≤ be a partial order over a set X and let f: X → X be a function over X. Then a prefixed point (also spelled pre-fixed point, sometimes shortened to prefixpoint or pre … See more In mathematical logic, fixed-point logics are extensions of classical predicate logic that have been introduced to express recursion.
