The pedantry in the comments here is astounding. Thinking about this geometrically it becomes clear the lecturer's intention is to communicate that x/0 and y/0 can be thought of as points existing at infinity. How people managed to turn this into some kind of ideological war is beyond me.
@@y.z.6517 No. x/0 is not infinity for any value of x. The limit of x/y, where y goes to zero approaches infinity. Anything besides zero divided by 0 is simply undefined.
@@ThefamousMrcroissant Your ex-friend borrowed $100 from you, and pays back $0 per day, and how long will he pay back? Infinite days. You need to start thinking beyond your primary school text book. Many school level knowledge is simplified white lies to make it easy for kids.
@@y.z.6517 I'm an academic physics undergraduate. You're the idiot here my friend. Let me put it in your own idiotic terms: if your ex-friend borrows 100 euro and you pay them back with 0 amount each timeframe, where you imply 100/0 = a, then a*0 = 100, where a is infinity, but this is a contradiction. Division by zero over any number besides zero is undefined. Nomatter how hard you try to argue otherwise it's not mathematically defendable to be anything else.
who tf start a video like "so the answer is " we don't even know what the question is

"Let's get offended cause we are a liberal society"
where is the next video?
Where is the *previous* one!?
possibly the worst explanation of homogenous coordinates on the internet
If only we would have the link on the previous and on the next video aswell as on the Ugacity course those vijs belong to ... !

This was so cool! Thank you.
Hate to be that guy but... dividing by 0 is undefined not Infinity.
@@howeichin4103 no it can't, dividing by 0 is not allowed.
@@howeichin4103 1/0=infinity, 0/0 can be anything.
