Inverse action: untying your shoelaces.

Work Step by Step

In loose terms, let f(untied shoelace)=tied shoelace. We want the inverse to be defined on tied shoelaces, g(tied shoelace)=untied shoelace So, g(f (untied shoelace)=untied shoelace and f(g(tied shoelace)=tied shoelace. [ f(g(x))=x and g(f(x))=x ] Inverse action: untying your shoelaces.
