Thank you so much for this. I've been beating my head against induction since I started caring about it (which was yesterday) and now I think I've got it. I wasn't getting the substitution of k^2 for everything left of the +1 term in the sequence, and now I am. I think you've helped clear a major block for me.
This guy is amazing! I was so lost when my professor taught it to me and even more lost when I tried to read the textbook. I only had to watch one example and it clicked right away!
The other videos didn't help me at all. But this video was the same exact problem I was stuck on. So when he explained each step it was extremely helpful!
Fantastic tutorial, keep up the awesome work! I was struggling with this at my Uni lectures and test, but I'm finally starting to get the hang of it. Thanks for keeping it simple.
@@designtip7268 hahaha, I did manage to pass the course and got my degree. Been working as a software developer coding pharmacy software for the past 7 years. I wish you luck man!
thank u soo much for explaining us in such abriliant way , you method and of teaching is very good , i like it ,you have cleared my concept about mathematics thanks again. A great love from PAKISTAN(the land of good hearted people).
good explanation; alot of people will skip the definitions in the beginning of the video.. i like how you explained it. it seems like others do not actually understand it but regardless they are unclear.
The induction step is not the assumption that something is true. The induction step has the form of an implication-IF the statement is true for k THEN it is true for k+1. That's why it's called a step.
Since both side are equal P(1) holds true, then it wouldn't matter if n^2 was on the left and (2k-1) on the right, correct? As in if they were swap you can still work with the RHS, meaning it doesn't matter whether you're using the LHS or RHS to show P(k+1) is true when adding/replacing n with (k+1)?
I saw your first video explaining Mathematical Proof by Induction and tried solving this problem by myself. Turns out I misinterpreted 'z 'for '2' in (zn-1) and laughed so hard at myself.
Sir good morning tq u so much i have one doubt sir i lost my original certificate in home shifting and i have taken duplicate from board will it useful for my job sir replay me
Think about it this way. k is simply a representation of the n value that we choose. For example in the cases n=1, n=2, n=3, k is the 1, 2, and the 3. So k+1 really just represents the next case. If k is 1 then k+1 is 2. If k is 2 then k+1 is 3. If k is 3 then k+1 is 4. So really (k+1) is how we would write the word "next", but with math notation. Now if we think about it as the word "next" rather than (k+1) it all starts to make some sense. If n=1 is valid (our basis step) then the "next" (n=2) is valid. If n=2 is valid then the "next" (n=3) is valid. If n=3 is valid then the "next" (n=4) is valid. and so on... All the dominos fall down. Now we can see that this works for any integer 1 or greater of our choosing.
but if you plug 2 in the formula you'll find that the number 3 you get is not = to 2 squared. I don't get it. 3 is not = 4. I mean it obviously works for 1, but how could it work for any other number? EDIT i get it now, you obviously sum it with the previous term
That is exactly the point. If we can't test for some large sample, why can't they, and I mean none of them will use the the second number. Maybe there's something they all take for granted.
Still dont get it. I get lost when you state that 1+3+5+...+(2k-1) + *(2(k+1)-1)* = (K+1). I know i'm missing something but i really dont know where (2(k+1)-1) came from. I know how you derived (2(k+1)-1) i just didn't understand why you had to add it to 1+3+5+...+(2k-1) if 1+3+5+...+(2k-1) is n = k, then, n = k + 1 would be 1+3+5+...+(2k-1) *PLUS* some representation of 1 wouldn't it. A bit confused here
+k2datrack Greetings from NK. If the last term in a series is n, then the term before it is n-1. If the second to last term in a series is g, then the last one is g+1. The term before (2(k+1)-1) is (2k-1)
I watched a bunch of these, and just now got exactly what I am supposed to assume. Thank you so much for the clear explanation and handwriting.
you are welcome
BEST math video on UA-cam about mathematical induction!
Thank you gents! In just 10 minutes you helped me understand this, which my professor failed to do in 150 minutes...
haha
YOU ARE A GOD SEND. I'VE WATCHED 10+ VIDEOS ON THIS AND I DIDN'T UNDERSTAND ANYTHING UNTIL YOUR VIDEO. THANK YOU SOOOOOOOOOOOOO MUCH!!
This is the best video on proof by induction that I have seen. I’m sharing it with my 12 year old grandson.😊
Thank you so much for this. I've been beating my head against induction since I started caring about it (which was yesterday) and now I think I've got it.

I watched 5 videos about math induction so far and among all of them this is the only video i understood. thanks
Wow, after spending so much time trying to figure this out after one course, your step-by-step explanation really broke this down for me. Thank you.
thank you so much for explaining where the k+1 came from, I watched the khan academy video and I was so lost. you explained it so much better
This guy is amazing! I was so lost when my professor taught it to me and even more lost when I tried to read the textbook. I only had to watch one example and it clicked right away!
I didn't even skipped the ads just to help you :D Thank you for sharing your knowledge.
Paul, thank you for this video. My "Night" just turned to "Day" with this Induction tutorial... Example was clear and very useful!!!
Thank you so much, To me it was the most understandable and detailed lesson on the Internet.
The best mathematical induction video on UA-cam. Now let me try out my exercises.
You are the only person who has made me understand induction so far. Thank you for your in depth approach. I wish others would follow suit
Cant stress enough on how much this video helped me through my first IB chapter!!
The other videos didn't help me at all. But this video was the same exact problem I was stuck on. So when he explained each step it was extremely helpful!
This is awesome! Was struggling in induction, but this helped so much! Keep making videos!!
Best video I’ve came across for prof by induction
Waaay better than my math teacher
Exactly!
Yep
I agree. Way better than our Computer Science Professor.
Finally the first person that makes sense in this subject
huge fan of his teaching skills. Thanks a lot for even explaining small steps that made it much easier to understand.
I've read through my notes so many times and never got it! I then watched your videos and it clicked immediately!
The best teacher
Fantastic tutorial, keep up the awesome work! I was struggling with this at my Uni lectures and test, but I'm finally starting to get the hang of it. Thanks for keeping it simple.
yo where you at man you watched this video 9 years ago you still alive? am taking quiz tomorrow that why am watching it

You legend!!! I actually understood this now thanks to you!
Thanks this is what I needed to understand this method
Nice work,,,,,,, simple and straight forward 😊😊
Thanks from Azerbaijan a lot 👍
this helped so much went from not understanding to BAM understanding
THIS HELPED A LOT ...BETTER THAN MY PROF
very clear explanation of the reasoning behind mathematical induction. thanks.
Zor zor gap yoq .l am uzbek .
Good vedio
You sir are a god! Understood them perfectly. Thanks a lot!!
Thank youuu youre a life saver to my assignment jusq
this is very good . induction understood fully !!!
You would make an amazing math teacher. Thank you very much
thank you soooo much, you helped me a lot 😃. I understand much better than my teacher.
good explanation; alot of people will skip the definitions in the beginning of the video.. i like how you explained it. it seems like others do not actually understand it but regardless they are unclear.
This is *magic*. Thank you so much for this helpful video!
You just earned a subscription brother
OMG!!! Hey sir, you taught is as simple as it is 🤓
wow, you have no idea how much this helped me :) keep making videos!
No kidding. It's like a cloud has been lifted from my mind.
this guy is gifted.
thank you so much for making these videos.
Superb Thanks a lot for the tutorial
you are awesome dude. TYVM before you came along this all seemed like magic to me lol
I can finally understand it, thank you!
I had to go here because my professors speaks quickly and I can't read his handwriting lol. I get it! Thank you.
6:44 literally what i needed
Thank you! I was so lost before this video.
Hi Paul, may I know how do you write these question on computer? I mean how do you record on computer.
Thank you so much for making this video. It helped me so much.
Why do you add (2(k+1)-1) instead of replacing k with (k+1)? 6:53
Thank you so much! You explained it in a way that was very helpful! You saved my ass! Literally!!
Bless you and your videos
Amazing thanks 😊
Thank you so much you make it easy
Way^2 better than my Math lecturer!!!!😉😂
Thanks so.much I now understand induction it remains recursion
The induction step is not the assumption that something is true. The induction step has the form of an implication-IF the statement is true for k THEN it is true for k+1. That's why it's called a step.
Thanks so much I understand now:)
Since both side are equal P(1) holds true, then it wouldn't matter if n^2 was on the left and (2k-1) on the right, correct? As in if they were swap you can still work with the RHS, meaning it doesn't matter whether you're using the LHS or RHS to show P(k+1) is true when adding/replacing n with (k+1)?
2k-1 can't exactly be replaced as it is the maximum sum/the rule but you could probably multiple both sides by negative 1 if you would prefer.
thank you! this was very helpfull!!!
Much appreciated lesson
great helpfull vid thanks
Patrick JMT step down, we have a new teacher
What program do you use?
can this be done the exact same way with recurrence relations?
gracias profe!
wow you made it easy :)
In induction, are we only to proof?
nice explain thank you
wow! thank you so much.
Make a vedio on question 7 plz....I really need it..
I saw your first video explaining Mathematical Proof by Induction and tried solving this problem by myself. Turns out I misinterpreted 'z 'for '2' in (zn-1) and laughed so hard at myself.
goooood stuff right there...
thanks you legend!
k^2 can any one answer this? What symbol that arrow up how to get that?
Sir good morning tq u so much i have one doubt sir i lost my original certificate in home shifting and i have taken duplicate from board will it useful for my job sir replay me
Where do we get K+1 from ?
Think about it this way. k is simply a representation of the n value that we choose. For example in the cases n=1, n=2, n=3, k is the 1, 2, and the 3.
So k+1 really just represents the next case.
If k is 1 then k+1 is 2.
If k is 2 then k+1 is 3.
If k is 3 then k+1 is 4.
So really (k+1) is how we would write the word "next", but with math notation.
Now if we think about it as the word "next" rather than (k+1) it all starts to make some sense.
If n=1 is valid (our basis step) then the "next" (n=2) is valid.
If n=2 is valid then the "next" (n=3) is valid.
If n=3 is valid then the "next" (n=4) is valid.
and so on... All the dominos fall down. Now we can see that this works for any integer 1 or greater of our choosing.
how do you prove when 1+3+5+7+...+ (2n-1)^2 =n^2
that cannot be proven if (2n-1)^2, it fails at the base case when we assume n = 1, it works for (2n -1) not squared.
can u plz prove it for the next element using n+1,instead of using k,i wanna see how does it works...
Thank you
thank you!
thank you so much.
hi
why is it 2k+1 + (2(k+1)-1) how does that carry over to other problems
THANK YOU!!!
Helpful!
but if you plug 2 in the formula you'll find that the number 3 you get is not = to 2 squared. I don't get it. 3 is not = 4. I mean it obviously works for 1, but how could it work for any other number? EDIT i get it now, you obviously sum it with the previous term
+Ozterkvlt You are confused.....
3+1 is equaled to 4
Its the sum of the numbers....
That is exactly the point. If we can't test for some large sample, why can't they, and I mean none of them will use the the second number. Maybe there's something they all take for granted.
I will pray to God for you, thank you
Can u make more videos.....
If n is a positive integer then 1/1.3+1/2.3+1/3.4+...+1/n(n+1)=?
Still dont get it. I get lost when you state that 1+3+5+...+(2k-1) + *(2(k+1)-1)* = (K+1). I know i'm missing something but i really dont know where (2(k+1)-1) came from.
I know how you derived (2(k+1)-1) i just didn't understand why you had to add it to 1+3+5+...+(2k-1)
if 1+3+5+...+(2k-1) is n = k,
then, n = k + 1 would be 1+3+5+...+(2k-1) *PLUS* some representation of 1 wouldn't it. A bit confused here
+k2datrack Greetings from NK. If the last term in a series is n, then the term before it is n-1. If the second to last term in a series is g, then the last one is g+1. The term before (2(k+1)-1) is (2k-1)
For the basis, if you did n=2 it doesn't work. You will get 3 = 4, and that doesn't work. Can you explain to me how n=2 would work?
same question here
When n=2
(2(2)-1)=3
2^2=4
How does this make sense?
Make sure you add all previous numbers.
omg thankkkkkkkkkkkkssss
But still I would love him to be my instructor instead😓
