    @DrSaucy @oantolin The textbook publishers are in bed with the university department heads to get them to require students to buy their textbook for their classes. They also make sure to reduce the amount of time that the book can be used in classes by releasing a new edition every year or two. The difference between the editions are usually just a few different exercises, maybe a chapter gets moved, nothing substantial

    @dnkboston oh because even thoughg'(x) = sin2(x) cos(x) => g(x) = sin3(x)/3is easy, then you'd have to integrate exp(x) sin3(x)/3 which would be … less easy 8-D

    Sometimes I wander into wonderful rabbit holes.This week's adventure, "What’s the fastest way to multiply two 32-bit numbers on an ARM Cortex-M0 CPU?"If you're thinking Karatsuba multiplication (https://en.wikipedia.org/wiki/Karatsuba_algorithm), you’re wrong.While Karatsuba offers a lower asymptotic complexity (around O(n^1.58)), it only pays off when used recursively on larger integers.On the Cortex-M0, Karatsuba runs much slower than the plain naĆÆve multiply. It turns out, simplicity wins at this scale.Godbolt Source:https://godbolt.org/z/4rP7bnv6r#programming #math
