NMAI069 (Mathematical skills) - just set theory nothing much of note.. next week we have a quiz

NDMI002 (Discrete mathematics) [lecture] - probability, defined the random variable and expected value of a random variable, trivial proof of linearity of expectation.. then markov's inequality, only used to prove chebyshev's inequality we'll see what use that has sometime else

NDMI002 (Discrete mathematics) [tutorial] - a quiz that i've made a small mistake on and also didn't write out that well, some problems on probability including the classic 20 people who don't share a birthday problem but also others like electronics with a fixed chance of being broken and sex assigned at birth, all pretty simple things

NTVY014 (Physical education I) [swimming] - we finally did proper backstroke, arms and legs and everything! and also breaststroke legs but on stomach, still no breaststroke arms though

NMAI057 (Linear algebra 1) [lecture] - attributes of inverse matrices, attributes of regular matrices, and matrix equations, after we started with groups and its axioms: association, neutral term and inverses.. also abelian groups

NMAI057 (Linear algebra 1) [tutorial] - quiz, i thought my solution was good but i must have made a small computational error because when plugging in my answer on the first row it was off by two and i didn't find the error, after the quiz we did proofs of matrix arithmetic statements, then matrix multiplication.. one is clearly easier, but either can appear on next week's quiz

NTVY014 (Physical education I) [swimming] - we had a swimming exam last week and i didn't swim 100m in 3:15 so i have to take swimming classes this semester, it was just the very basics for now, which i know, i am capable of swimming, just not very good at it

NMAI057 (Linear algebra 1) [lecture] - we went over how to solve a matrix, then homogeneous and inhomogeneous matrices and how they relate, that you can solve a homogeneous one generalised then get a single solution of the inhomogeneous one and add the resulting vertices together to get all the solutions of the inhomogeneous one

NMAI057 (Linear algebra 1) [tutorial] - we started with a quiz, it was very straightforward, we were given three non-collinear points on a plane a had to get a parabola through it.. i failed however, made a small mistake and noticed it too late to fix it.. after the quiz we did a few matrices, some homogeneous some not, it's rather simple
