Mathematical Induction Proof with Sum and Factorial

[@justamoose220]

This is literally the exact proof I was stuck on for an assignment. You're a lifesaver. Thank you.

[@TheMathSorcerer]

Oh wow how random haha. This is from a random number theory book I think.

[@ashk3734]

@@TheMathSorcerer well I was stuck on this for ages as I didn't know that n!(n+1) is n! thanks for helping out

[@theplumpchicken2233]

Same lol 😂

[@noorbano1306]

Same guys i asko stuck in this same question Hahahah

[@wasntblessedwithone7488]

5:49, Agreed. I don't work with factorials very often in an algebra setting so this video was a godsend, thank you!

[@TheMathSorcerer]

Glad it was helpful!

[@alfiehiscox3732]

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!!

[@aidanlynch8415]

searched "proof by induction factorial" and this was the exact problem I was stuck on in my textbook lol, thanks!

[@Thecoolguy43]

Thanks for posting, ive been meaning to brush up on my math

[@dougjordan1544]

thanks, the factorial identities are not often mention and are assumed. You stated them which made it far easier to prove.

[@noorbano1306]

Amazing explanation Sir g

[@assails5705]

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 👏🏽✨

[@TheMathSorcerer]

You are welcome!

[@beautifulaffliction1742]

You’re the best bro.

[@limkangjay1439]

my lecturer just say, "this question is for your exercise " BTW thanks a lot, you helped me to solve this question

[@JamesMatimela]

Long Live Bro ✊🏿❤️

[@cretorn1]

This was in the test and it wasn't taught...

[@noorbano1306]

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

[@fatinonari8333]

That was my exercise qs and I was stuck here but you got me out Thanks Alot ❤️

[@franciscotomasmorenogarcia2913]

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.

[@TheMathSorcerer]

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)!

[@georgettebeulah4427]

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.

[@TheMathSorcerer]

You are welcome!

[@WhishoMH]

Super helpful

[@delpear_]

idk how you can write like that but tysm for this proof!

[@tommyphu307]

omg thanks so much:) was stuck for a minute

[@eduidearamlan]

Thank you, very helpful

[@valentiabusi436]

Thanks for the video ❤

[@TheMathSorcerer]

You're welcome 😊

[@loveyourself1581]

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!!!

[@krishivrana8272]

🤘👍🤘

[@krishivrana8272]

Where are you from?

[@TheMathSorcerer]

I'm in the US currently

[@ylh4117]

Thx you saved me

[@explorenxaencantaja1093]

Thank you.

[@TheMathSorcerer]

You are welcome

[@kainatjaved4622]

I understand video except last points...

[@leanneteh8307]

thank you!!

[@TheMathSorcerer]

You are welcome!

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.

[@Michael-jt2xi]

Are you sure? It seems to work for n = 1, 2, 3, 4.

ur a beast
