Back to the Linear Algebra for Quantum Computing series, with sheet number four! In this one, I cover set theory notation, Cartesian product, relations and functions, as well as what it means for a function to be injective, surjective, and bijective.

UPDATE 08.31.2022: Since these sheets are now complete, styled, reviewed, edited, and published, you can pick up the whole pack of 15 in my shop here!
