Daily Integral 17 February 2026
Prelude Wow, all of today’s integrals are so easy. The medium was only a binomial expansion simplification or using polynomial division. This medium is not worthy of medium. Done the first hard in... -
Daily Integral 16 February 2026
Prelude Yeah, I really don’t like King’s Rule. It just feels like it came out of nowhere. I was struggling until I used the hint. I guess it is very useful but I just can’t see it sometimes. Begi... -
Daily Integral 15 February 2026
Prelude Pretty nice integrals in general, nothing too hard. The medium got me stuck because I didn’t recognise the integral is simply a u-sub with eee and cotx\cot xcotx at the end. Beginner Int... -
Daily Integral 14 February 2026
Prelude Beginner and Easy integrals are all pretty easy. I was stuck at the medium integral due to not knowing the King’s property. This property seems quite random to me, not used to it yet. Beg... -
Daily Integral 13 February 2026
Prelude The easy integral was really hard for me since I didn’t know the standard form (not taught in school), and couldn’t integrate secθsec\thetasecθ either Beginner Integral I=∫23x(x−2)4 dxLet... -
Daily Integral 12 February 2026
Prelude The beginner and easy are both fine today, but damn what the hell is the medium integral. Got some help on discord and friends to do it. Beginner Integral I=∫12e1xx2 dxLet u=1x, dudx=−x−2... -
Daily Integral 11 February 2026
Daily Integral 11/02/26 Not the hardest integrals, but still do hard integrals yet. Got into this because all my friends are doing it. Beginner Integral I=∫0π3sec x(sec x+tan x) dx Expand the bra... -
Parametric Equations and Vectors
Prelude New year, and I am now in year 12, learning more vectors… In tutoring today, I did some 3D vector problems containing parametric equations. I’m going to post my solutions here. Problems ... -
Initial Thought on Vectors and SIMD
Prelude Recently, due to past learning on ray-tracers, vector maths, and hearing about SIMD everywhere, I became interested in implementing a small Linear algebra library as a holiday work. Curren...
