|  | ## Inner Product Spaces
 | ||
|  | 
 | ||
|  | ### Introduction
 | ||
|  | 
 | ||
|  | Let V be a vector space over field F. An inner product is a function that assigns to every ordered pair of vector x and y in V, a scalar in F, denoted by <x,y> such that for all x,y in V and a in F these hold: | ||
|  | 
 | ||
|  | * <x+z,y>=<x,y>+<x,z> | ||
|  | * <ax,y>=a<x,y> | ||
|  | * <X,Y>=<y,x> (X and Y denote conjugate of x and y respectively) | ||
|  | * <x,x>=0 for all x!=0 |
