Given a map f:S->T between sets S and T, the map g:T->S is called a right inverse to f provided that f degreesg=id_T, that is, composing f with g from the right gives the identity on T. Often f is a map of a specific type, such as a linear map between vector spaces, or a continuous map between topological spaces, and in each such case, one often requires a right inverse to be of the same type as that of f. If f has a right inverse… 2 It will look like this [ A | I ]. It can also provide the calculation steps and how the right triangle looks.
