What is s1 circle?
Frequently, especially in trigonometry, the unit circle is the circle of radius 1 centered at the origin (0, 0) in the Cartesian coordinate system in the Euclidean plane. In topology, it is often denoted as S1 because it is a one-dimensional unit n-sphere.

Definition 12.2:
We define T={z∈C||z|=1}; T is a group with respect to multiplication in C and is called the circle group. Note that geometrically T is the set of complex numbers which are at a distance 1 from the origin, that is, it's points are exactly the points on the unit circle x2+y2=1.
What is a group in sets?
In maths, a group is the combination of a set and binary operation. For example, the set of integers with an addition operation forms a group and a set of real numbers with a binary operation; addition is also a group. These satisfy some laws, say closure, associative, identity and inverse to represent as a group.
What is the order of the circle group?
As we already know, the circle group has infinite order. It's also intuitive for me that this subgroup also has infinite order since there are infinite rational numbers between 0 and 2π and thus there are infinite complex numbers z=cosθ+isinθ.

What is 2 groups of 3?
A group is a set combined with an operation that follows four specific algebraic rules. So, you see, a set on its own is not necessarily a group, but a set that is combined with an operation and follows the rules is a group.

A group is a finite or infinite set of elements together with a binary operation (called the group operation) that together satisfy the four fundamental properties of closure, associativity, the identity property, and the inverse property.

An oval is an elongated shape that is round and has no sides or corners. It is closely related to a circle shape, but it appears more stretched-out and is not evenly curved. Imagine a beach ball that has been squeezed on two sides.
What does C mean in a circle?
A circle is not a polygon. A polygon is a shape bounded by a number of straight lines. If any side of the shape is curved then it is not a polygon. Because a circle is curved and has no line segments, it does not meet the criteria for being a polygon.

Circles class 9 – The collection of all points equidistant from a fixed point in a plane is called a circle.
Is A circle A polygon?
Lines and circles are the most elementary figures of geometry − a line is the locus of a point moving in a constant direction, and a circle is the locus of a point moving at a constant distance from some fixed point − and all our constructions are done by drawing lines with a straight edge and circles with compasses.
What is a circle Class 9?
Most of the circle work would clearly not be trigonometry. But circles are useful to understand the trigonometric ratios. And the geometry of circles often involves work with triangles. The result is a fuzziness where the terms geometry or trigonometry could both be used and both be correct.

While the circle has no beginning or end, the curve, as part of the circle, can insinuate a direction and orientation, and can also imply movement.

So, to show S2 is not a Lie group, it is sufficient to show that every homeomorphism of S2 which is homotopic to the identity has a fixed point. In fact, any continuous map (be it a homeomorphism or not) of S2 has this property.
Does a circle have a end?
To the human eye, circles and spheres are abundant in nature and in our universe. They can occur naturally — in planets, stars, celestial bodies, tree rings, rain drops — or they can be man-made — such as traffic roundabouts, buttons, volleyballs, pizza.
Why S2 is not a Lie group?
For a circle to be perfect, we would need to measure an infinite number of points around the circle's circumference to know for sure. Each point would need to be precise from the particle level to the molecular level, whether the circle is stationary or in motion, which makes determining perfection a tricky feat.

Being a group requires the existence of an identity element, and since the empty set cannot satisfy this (it has no elements) it is not a group. As BrianO says, ∅ is not a group, because every group has an identity element.

A subset is a set that only contains elements from a larger set (called a superset). For example, {0, 2} is a subset of {0, 1, 2, 3}. A subgroup is a subset of a group that also has group structure (associativity, closure, inverse, identity) and inherits the binary operation from the group.
Is null set a group?
An algebra in the first sense, as well as a group are special kinds of algebras in this way. A group is an algebraic structure with one binary operation, an inversion operation (a unary operation), and a neutral element (a nullary operation), fulfilling some rules (e.g. associativity of the binary operation).
Is a set a subgroup?
All elements of a group have an inverse. This is a requirement in the definition of a group. For an element g in a group G, an inverse of g is an element b such that gb=e where e is the identity in the group.
