 Definition: 
  1. \In*verse"\, a. [L. inversus, p. p. of invertere: cf. F.
    inverse. See {Invert}.]
    1. Opposite in order, relation, or effect; reversed;
       inverted; reciprocal; -- opposed to {direct}.
    
    2. (Bot.) Inverted; having a position or mode of attachment
       the reverse of that which is usual.
    
    3. (Math.) Opposite in nature and effect; -- said with
       reference to any two operations, which, when both are
       performed in succession upon any quantity, reproduce that
       quantity; as, multiplication is the inverse operation to
       division. The symbol of an inverse operation is the symbol
       of the direct operation with -1 as an index. Thus sin-1 x
       means the arc whose sine is x.
    
    {Inverse figures} (Geom.), two figures, such that each point

       the radius.

 Definition: 

Given a function, f : D -> C, a function g : C -> D is called a left inverse for f if for all d in D, g (f d) = d and a right inverse if, for all c in C, f (g c) = c and an inverse if both conditions hold. Only an injection has a left inverse, only a surjection has a right inverse and only a bijection has inverses. The inverse of f is often written as f with a -1 superscript.
