@@clap_lmao I’m in high school and I had to do them for Calc II at the beginning of the school-year. The only difference is we were taught it with including the density constant in the (now) mass and moment formulas, even though they cancel out. I presume it was in order to understand if/when we actually need the proper mass/moment for other formulas?
AHAAH!! I can show this to the civil engineering students and prove they need to do calculus! They were hassling because it was only the electricals that had to do higher math, ahaha I'm so happy! :D
I just finished my A levels and Im learning calculus myself before I go into uni. I'm thinking what if I connect infinitely many centroids of each rectangle and then find the median along the x and y axis since mass is assumed to be distributed equally. Would that work?
#Yay. The question I recently had in mind was a bit related to probability... What happens to the probability of getting a number divisible by 5, as you move from 1-digit numbers to 2-digit numbers, to 3 to n-digit numbers? And as n approaches infinity?
I just thought of an interesting question or at least I think it is. Is the sum of sequence of x^(1/x) when x approach infinity ♾ starting from one is it diverges or converges. and if it is converges can you tell us the value of it. I thought of one method that thought us which is convert it to an integral and worked out and see if it converges then the sequence is conv too. But this integral is not elementary so. but at the end I think it is diverges because if we graph it. The area under the graph is ♾ .
@@alimghazzawi3700 x^(1/x) approaches 1 for x -> infinity. 1+1+1+... can't possibly converge to a finite value, you don't need any integral to prove that.
@@willnewman9783 The video "e as an infinite sum (using binomial theorem)" appeared among my notifications but was then withdrawn for some reason. It will probably appear again later. Maybe there was some technical fault or a rare mistake in the maths.
@@AnonimityAssured Oh okay, I thought you meant something like that. Yeah, I saw that video yesterday. I noticed there was a part in the video that, while mostly correct, needed a bit more justification than what he gave. I am guessing he is refilming it adding further explanation
blackpenredpen Yeah, its quite crazy to me how we have a 4 month summer break compared to the 2 month break we get in high school. I have a Linear Algebra exam next week and then im done!
Actually we have that area multiplied to the object's surface density . But since we have surface density term taken out common on the numerator as well , it gets cancelled . He mentioned it in the beginning of the video .
moment of inertia is an analog for mass in rotational motion. The higher the moment, the lower the acceleration of an object around an axis. If you play around with the formula for kinetic energy, you can find out how to calculate it.
I really admire your vids a lott.!! you explain beautifully. but i hv a doubt, can you show how to do this by horizontal strip of area? im facing trouble in it..
Wow, It's like you know what topics I need to revise! Your upload schedule is perfect!
Rahmed hahaha : ))))
@@blackpenredpen please pick up my challenge on pathreon 😭
I would like to say this man is single handed lay keeping my grades at an A
I was stuck in a calculus problem for a day until I met this explanation, thx bro
so glad i found this channel! you explain things so nicely it's very easy to understand
Thank you so much! Your videos are so helpful. You are a great teacher and the examples are short and very direct
I just finished high school math. I feel smarter from this video already.
you did centroids in highschool tf im doing them in statics engineering rn xD

Perfect for last minute revision
Ahhh mathematics is so fabulous😮
Hi, I love your videos and channel! Would you consider covering Cauchy principal value? I find it really interesting but I don't understand it 😂
This is really helpful 🥺❤️
Wow ! Amazing video. I didn't know this.
THANK YOU SO MUCH MY FINAL EXAM IS TOMORROW
good tutor.
Nice to learn new stuff thank you 1/(1-x)
Geetha Udupa : )
I really like these centroid videos. You should make more!
Have you ever use statistics to check on the relativity of certain formula?
You make me believe in UA-cam
Very helpful
Thank you
beautiful
You are awesome

And as n approaches infinity?
THANKS 😊
Thank you!
Collab with Eddie woo would be interesting.
Maaaan pick up my challenge on pathreon!
Cycloids nest please!and the derivation of 3pir^2
Just before my static test !! coincidence? I do not think so
That looks sorta similar to the mean value theorem I learned last semester
Berry cool
Do video on gaussian integral please
Dr Peyam has done twelve of them recently!
for y bar, can we use the inverse function?
Great, some idea how to prove and find the intersection of f (x) = e ^ x and g (x) = tg (x). ? ...

Porhaps May be you show us a ramanojan solution
You can just do the test for divergence, x^(1/x) doesn't approach 0.
Sensei. Its a sequence if we use the integral method that he showed us you can’t worked out because how can you integrate x^(1/x) at the first place

Sensei I know i wrote that at the end of
the first comment . I am interested on if there is a ramanojan solution or a solution that is like -1/12
Can I use integral double? (sorry for my English)
I was about to wake up then this video appears
I am in 9th :( , but still love your videos :)
Sorry, but what happened to the video "e as an infinite sum (using binomial theorem)"?
I would also like to know
How can I concentrate on this when I'm thinking of "e as an infinite sum"?
truee lol
What do you mean?

I was so confused because I watched it earlier and then it suddenly wasn't there, at least I'm not going crazy...

tldr
but do i do integral f(x) - integral g(x)
too late... just had my calc 2 final exam last week lol
Clumpy. Are you on quarter?
blackpenredpen I go to UBC in Vancouver, basically the normal school year is two semesters, September-April with April being exam period.
Clumpy
Oooh I see. No wonder. I thought you would be on a quarter system
blackpenredpen Yeah, its quite crazy to me how we have a 4 month summer break compared to the 2 month break we get in high school. I have a Linear Algebra exam next week and then im done!
Clumpy 4 months break!!!!!!!! Now I am jealous!! Oh, and you can check out dr. Peyams channel for linear algebra true false problems!!
Why are you dividing by the area? I don't understand.
Its a rule
centroid= sum(area*distance)/sum(area)
It's a weighted average of all the points inside the funtions, based on their areas.
Actually we have that area multiplied to the object's surface density . But since we have surface density term taken out common on the numerator as well , it gets cancelled . He mentioned it in the beginning of the video .
Uploaded 30 minutes after my statics final...
Nice but you should have explained what is a moment first... I'm still not sure what it is. :/
moment of inertia is an analog for mass in rotational motion. The higher the moment, the lower the acceleration of an object around an axis. If you play around with the formula for kinetic energy, you can find out how to calculate it.
what was the video about, you deleted.

I don't understand why I sing BPRP in the same tune as PPAP🙄
Um Hi
All of his videos are clearly clickbait. See, he uses black MARKERS and red MARKERS, not blackpenredpen
