O'Mighty Sorcerer, you've done it again! I was ready the Skiena book 'The Algorithm Design Manual' and was getting stuck on induction and this exact proof. Safe to say it's making a lot more sense now! Thanks!!
Its really very helpful My teacher gave me homework which is this question i was going wright but in ! I stuck then i thought let search may be i got any hint of that But look my goodness i got same question Thanks boss
The only thing keeping me from understanding it to the 100% is (k+1)! * (k+1), why is equal to (k+2) ?? I'm not well verse in factorial and tired of searching, if someone could explain or post an url, whatever that could help, thanks i advance.
This statement is not true for n= 1,2,3,4 . I just tested for these numbers. I do know, but this statement might not be true at all. It is only true for n=1.

This is literally the exact proof I was stuck on for an assignment. You're a lifesaver. Thank you.
Oh wow how random haha. This is from a random number theory book I think.
@@TheMathSorcerer well I was stuck on this for ages as I didn't know that n!(n+1) is n! thanks for helping out
Same lol 😂
Same guys i asko stuck in this same question
Hahahah
5:49, Agreed. I don't work with factorials very often in an algebra setting so this video was a godsend, thank you!
Glad it was helpful!

searched "proof by induction factorial" and this was the exact problem I was stuck on in my textbook lol, thanks!
Thank u sooo much...It was same question in my assignments and I got confused at last steps..this was really helpful..u r the best thank u 👏🏽✨
You are welcome!
thanks, the factorial identities are not often mention and are assumed. You stated them which made it far easier to prove.
Thanks for posting, ive been meaning to brush up on my math
You’re the best bro.
my lecturer just say, "this question is for your exercise "
BTW thanks a lot, you helped me to solve this question
Amazing explanation Sir g
That was my exercise qs and I was stuck here but you got me out
Thanks Alot ❤️
Its really very helpful

But look my goodness i got same question
Thanks boss
idk how you can write like that but tysm for this proof!
Long Live Bro ✊🏿❤️
This link video you write I can understand from it a lot if you make more math lectures will be much better or easier. Thank you so much.
You are welcome!
omg thanks so much:) was stuck for a minute
Thank you, very helpful
Super helpful
This was in the test and it wasn't taught...
Thanks for the video ❤
You're welcome 😊

Ok so n! = n(n-1)(n-2)(n-3)*...*3*2*1, ok so here we have
(k + 2)*(k + 1)! =
(k + 2)(k + 1)k * ...*3*2*1 =
(k + 2)!
In general,
(n + 1)n! = (n + 1)!
i have a question. What if n, the upper limit of summation is stated to be equals to 1 would it be the same? Btw thank you for this!!!
🤘👍🤘
Where are you from?
I'm in the US currently
Thx you saved me
Thank you.
You are welcome
thank you!!
You are welcome!
ur a beast
I understand video except last points...
This statement is not true for n= 1,2,3,4 . I just tested for these numbers. I do know, but this statement might not be true at all. It is only true for n=1.
Are you sure? It seems to work for n = 1, 2, 3, 4.
why tf do you hold the market like that
You look like Jeff Bezos
