Equivalence (mathematics) | Binary relations | Vectors (mathematics and physics)
In Euclidean geometry, equipollence is a binary relation between directed line segments. A line segment AB from point A to point B has the opposite direction to line segment BA. Two parallel line segments are equipollent when they have the same length and direction. (Wikipedia).

What is an equiangular triangle
👉 Learn the essential definitions of triangles. A triangle is a polygon with three sides. Triangles are classified on the basis of their angles or on the basis of their side lengths. The classification of triangles on the bases of their angles are: acute, right and obtuse triangles. The cl

Finding Eigenvalues and Eigenvectors
In studying linear algebra, we will inevitably stumble upon the concept of eigenvalues and eigenvectors. These sound very exotic, but they are very important not just in math, but also physics. Let's learn what they are, and how to find them! Script by Howard Whittle Watch the whole Math

Does Consciousness Exist? (By William James)
William James' wonderful 1904 essay "Does Consciousness Exist?" where he puts forward a kind of neutral monist view of the mind. This was read by D.E. Wittkower and is from LibriVox. The paper itself comes from William James' "Essays in Radical Empiricism", which was published posthumously

Isosceles & Equilateral Triangle Properties
I introduce 2 theorems about the properties of Isosceles and Equilateral Triangles. These theorems discuss how the base angles are congruent and that the bisector of the vertex is also a perpendicular bisector of the base. This video includes 2 proofs and 2 algebraic examples. EXAMPLES

What is Mathematics, Really? #SoME2
