I integrate random stuff and mess around with some other exotic math ideas.

    ive been trying for a few weeks to blindly get a line segment rotating at one endpoint, but i just couldn't figure it out (i knew it had to do with y=tan(a) but i didn't know what bounds i should insert) then i figured, maybe i just look up how to make a clock! and there we have it (thanks!)

    Maybe I didn't understand it very well, why the Psi 1 and Psi 2 don't they cancel here? In the residue theorem proof something like that used to be cancelled

    If i want to reflect relative to what a is, i.e. if y = x then a = 1 and then we have ((1, 0), (0, -1)), does this mean ((1,0),(0,-a)), so i.e. a = 2 means ((1,0), (0, -2)) ?

    Hi, loving the videos so far! I also have a question: at 15:08 you say to simply assume the existence of a C^k atlast, but how does that work in practice? Surely you can't just assume one to exist out of the blue.

    For a simpler method, substitute u=1/x , move around some things and replace u with x and you'll see that the integral is equal to its negative

    Can't you say that 1/abs(z^4+1) <1/abs(z^4) ? Simply because the right fraction has a smaller denominator, without going into triangle inequality stuff

  • @qncubed3
    @qncubed3Ай бұрын

    This only works if z^4 is positive. If z^4=-2 for example then you would get 1<1/2

    5:34 It's easier not to reduse (s+i) or (s-i) because (i+i)^4 or (-i-i)^4 is 16, so thier denominator becomes rational.

    Much easier with double integration I = \int_0^\infty \int_a^b sin(tx)/x dt dx = [using Foubini] = \int_a^b \int_0^\infty sin(tx) / x dx dt = \int_a^b pi/2 dt = pi/2 * (b - a)
