I love that at 3:15, once you start explaining "The part you are going to hate with a fiery passion," a small child starts aimlessly howling in the background. You and I are on the same page, little buddy.

"You're either going to love or hate with a fiery passion"..."Most people hate it with a fiery passion".... The few that do love it are psychopaths

You are such a great teacher! for so many reasons but one of them is because you humanize this math. You make this math seem less cold and less sterile, into something more natural.

Thank you for explaining this properly. The other inequality proofs I found on KZbin were bugging me, because it felt like they were skipping steps or cheating. Now it makes sense thanks to you!

Thank you so much for the in depth explanation on inequalities and how you converted 1 to 2^k to 2^(k+1). Your videos are helping a lot!

Thank you!!!! This is the only video that actual helped me understand how 2k+1 can become 2k + 2k and so on.

3:34-4:46 is her employing logic from the solution established at the basis step: 1 < 2^1. This solution is then modified to 1 < 2^k on the inductive step, where the inequality is then used to say that if 1 is less than 2^k, then 1 can be replaced with 2^k in an inequality where 1 is greater than some value: it implies that 2^k is also greater than that value, and so the inequality holds.

For the second proof, could you not just substitute k! or 2^k like so 2^(k+1) < (k+1)! 2*2^k < k! * (k+1) (using consecutive neighbours) sub in k! for 2^k or 2^k for k!, both will work, I choose 2^k in this case (remember we assume 2^k < k! 2*(k!) < k! * (k+1) cancel out k! 2 < (k+1) Therefore since we stated the predicate function was true for all k part of the set of positive integers and k equal to or more than 4, k+1 will always be more than 2 as the minimum k+1 can be is 5 Would this be wrong and if so could anyone point out why, maybe I am using circular reasoning or something, but I don't think I am since I am not assuming 2^(k+1) < (k+1)! is true, i am proving it is. If you could please explain whether this would be right that would be amazing, thank you for the video by the way!

So essentially we're showing that P(k) = P(k+1) right?

@ashrafulislam78253 жыл бұрын
Thank you so much for this! However, I had a question. At 8:50, if we write 2^k+1 < 2k! < (k+1)k! then 2^k+1 < (k +1)k! this is also okay, right?
@argav625 Жыл бұрын
8:20 I wonder why would you come up with the "k+1>2" ? I mean, yes I understand you want to get to the "(k+1)!", but why it must be "k+1" to be greater than '2'? Is "(k+1)>2" just the assumption or something?
