Inverse \In*verse"\, adjective [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 or angle whose sine is x.
