Math is fun if you make it fun lol… no but seriously, math can be pretty hard sometimes so I tried my best to explain most of it in a interactive and funny way, hope you enjoy it 🙂

You have good sense of humour
i have my calculus exam in an hour let's see how it goes!!!
interesting and informative.
your the new wacky science
I’m a minute and a half in and I’m already lost.
11:40 IT ALL MAKES SENSE NOW
stochastics was really really short and number theory wasn‘t even mentioned
0:48 an equation doesent need a variable to be an equation
14:01 x≈−0.7549 ?
x^5 + x + 1 = 0
Let w be a root of the equation, then
w^5 + w + 1 = 0
Consider the powers of w in the LHS, then notice that {5,1,0} = {2,1,0} (mod 3), and {2,1,0} is a complete residue system mod 3
So, (x^2 + x + 1) | (x^5 + x + 1)
x^5 + x + 1 = (x^2 + x + 1)(x^3 – x + 1)
Hence, x = -1 + i*sqrt3/2, -1 – i*sqrt3/2
or
By Cardano, x^3 – x + 1 has roots
cbrt(2/(3(9 – sqrt69))) – cbrt(9(9 – sqrt69)/2)
We can use this result to get the two other complex roots easily. qed
