<x, y> : vector (x, y) (x, y) : vector (x, y) A_1 : A subscript 1 A-> : vector 'A' ->(A) : vector 'A' |A| : Magnitude = sqrt(a_1^2+a_2^2) which is the euclidean distance from the origin (0,0) |A| (A in italics) : det() : determinant cos(a) : cosine of angle a A . B : A and B Dot Product A * B : A and B Multiplication 90* : 90 degrees @ : angle pi = 180 degrees = 3.14 _|_ : orthogonality symbol |u| : |unit vector| set() has same notation as magnitude, | | , but has multiple rows. A' : A' prime (modification of original A, not first derivative of A unless otherwise stated) a_^ : symbolic variable 'a'
NOTE: if someone can help convert the notes to better formatting that would be appreciated! I prefer latex formatting unless someone knows of a better one.
If there is something confusing about the notation leave a comment on this page
