I can appreciate that you profess to like math, but the equation you list is fairly meaningless- cos(u)=cos(x+pi/2) just implies u=x+pi/2+n2pi, n any integer. Then that=-sin(x) is just an application of the cofunction identity, with the oddness of sin. I also don’t understand what you purport to mean by “negated mechanical thought of the human brain” or “the ruby charm that we need”. I am totally in agreement with the awesomeness of math, though.

This video is so long and great that I came 5 times ❤
