Vectors, Algebraic Properties such as Positivity u∘u≥0 and u∘u=0⇔u=0, Vectors can be written as row vectors, Orthogonality means The angle between two vectors, Vectors can be written as column vectors, |u+v| ≤ |u| + |v| which means that visually The length of one side of a triangle is always less than or equal to the sum of the lengths of the other two sides, n-tuples or coordinates e.g. (a,b,c,d,...,e) or Position Vectors, Orthogonality means <math xmlns="http://www.w3.org/1998/Math/MathML"> <mrow> <mtext> u∘ </mtext> <mtext> v </mtext> <mtext> = 0⇔θ=90 degrees </mtext> </mrow> </math>, Direction Every direction has a component Components, Vectors obey The Triangle Inequality, The Dot Product which consists of <math xmlns="http://www.w3.org/1998/Math/MathML"> <mrow> <mtext> |u|^2=u∘u </mtext> </mrow> </math>
