the best part was when the equation went off the screen. I'm kidding. What I want to know is how do you know how the arc should be drawn?

He just means the ratio of l/w which turns out to be 1 + root 5 over 2: then he just divided to get the decimal.

he needs to be consistant where he makes his new smaller rectangle so the curve is accurate. But good explaination anyway. Q. How did pathagarus come up with the 3,4,5 therom

also the inverse of the golden ratio 1/1.618 is the one less then the golden ratio 1.618 - 1so if you do 1/x = x-1 you also get it

You can find the golden ration easily by finding the positive solution of the quadratic equation x^2-x-1 = 0.Use the quadratic formula and you get (1+-sqrt(5))/2

He says, "postage stamp." Twice. Did you mis-hear or were you trying to be funny?

hahaha LOL!

well if u get one of the answers (which i typed in brackets) and then divided it by the previous answer (in brackets) u get 1.618. eg: 55 divided by 34 = 1.618 or even: 34 divided by 21 = 1.618. That is, 1.618 is called the golden ratio/mean. it is seen in nature pretty much everywhere! the guy in this video is just showing how to work it out and look at it 'visually'
