koku's life journal

alright, i've put off writing blog posts for a bit, but i'm back!! gonna write all of monday to thursday right now on the train

NMAI069 (Mathematical skills) - had a quiz on propositional logic, was simple, after that we went over something or other..

NDMI002 (Discrete mathematics) [lecture] - finished binary relations with the theorem "about the long and broad" proving that the product of the width and the length of a partially ordered is greater than or equal to the its size, then we started with combinatorial counting, permutation is bijection of X -> X, then something about power sets

NDMI002 (Discrete mathematics) [tutorial] - a quiz, i felt rather confident with my solutions, but then the teacher wrote the best solution and they were much more elegant than mine.. after we did some exercises on functions and equivalence relations and didn't have time to get to the partially ordered sets
