Algebra, chapter II, § 2. Modules of linear mappings. Duality

Let E, F be two A-modules each with a finite basis, E (resp. F) being canonically identified with its bidual E (resp. F). Then, for every linear mapping u : E → F, ttu=ut^t u = u.

This follows immediately from the commutativity of diagram (27).

Bourbaki puts the proof directly after the statement, so what is above is the statement and its proof together.
