Antipodal point

In mathematics, antipodal points of a sphere are those diametrically opposite to each other (the specific qualities of such a definition are that a line drawn from the one to the other passes through the center of the sphere so forms a true diameter). This term applies to opposite points on a circle or any n-sphere. An antipodal point is sometimes called an antipode, a back-formation from the Greek loan word antipodes, meaning "opposite (the) feet", as the true word singular is antipus. (Wikipedia).

Find the midpoint between two points w(–12,–7), T(–8,–4)

πŸ‘‰ Learn how to find the midpoint between two points. The midpoint between two points is the point halfway the line joining two given points in the coordinate plane. To find the midpoint between two points we add the x-coordinates of the two given points and divide the result by 2. This giv

Find the reference angle of a negative angle

πŸ‘‰ Learn how to find the reference angle of a given angle. The reference angle is the acute angle formed by the terminal side of an angle and the x-axis. To find the reference angle, we determine the quadrant on which the given angle lies and use the reference angle formula for the quadrant

AlgTop14: The Ham Sandwich theorem and the continuum

In this video we give the Borsuk Ulam theorem: a continuous map from the sphere to the plane takes equal values for some pair of antipodal points. This is then used to prove the Ham Sandwich theorem (you can slice a sandwich with three parts (bread, ham, bread) with a straight planar cut

The Borsuk-Ulam Theorem | Nathan Dalaklis

Mappings and functions that work on topological spaces other than the real line can be counterintuitive, and in cases like with the sphere, we have things like the Borsuk-Ulam Theorem which can assert the truth of things that would appear, without proof, to be outright lies. In this video,
