Prof, Why have you not discussed section 2.5?

[@aylindoganoglu9306]

Did you mean "a pivot in every column" since I cannot find anything regarding the number of rows in the invertible matrix theorem?

[@cricketfacts822]

CRAMER'S RULE, VOLUME, AND LINEAR TRANSFORMATIONS ???

[@sepalabola-zh6hz]

Could you please tell me what does one to one means, does it means it has to have an unique solution???

[@SawFinMath]

I suggest finding my video on one to one and onto functions and the one on uniqueness

[@tristessed]

2.5?
