Still looking but favorite ending so far!
I think it's very cute! thanks sir. Subed and liked
That was a good lecture. By the way, that t-shirt is awesome!
team quadratic
I didn't even know that was a team!
Nice
thank you sir
Thank you so much for making this! This was super helpful in studying for my linear algebra final.
No problem, Big Steve!
Why do you use the area formula when it asks for perimeter
We want to find the maximum area for a slice with a certain perimeter.
Linear algebra reference 🤩
I hope you're studying up this material so you tutor the course :)
I've been through linear algebra long ago, but it didn't start clicking until recently. I appreciate your effort sir
That's great! Thanks for watching :)
When doing point slope form, should I simplify the equation past y+2 =2/3(x-1) or would leaving it like that be ok?
Leaving it as y+2 =2/3(x-1) is good, but it might be better to subtract over the 2, so y =2/3(x-1)-2. No need to simply any more than this.
it is -4 and +3 when you split the equation, and the answer should br negative 1/7
Nope it's n+2
I couldn't disagree more!
I did sip my coffee at the same time, thank you
Approximate gravitational constant in Minecraft
I already did! Check out my old videos.
@@DrWeselcouch oh didn't realise that
I did sonething simmilar today amd i thaught anyone else had this idea I used counted the blocks inside to calculate pi My approximation was 3.21875
Very cool!
@@DrWeselcouch ill upload the video today
@@PriggarGaming Can't wait to see it. Let me know when it's up :)
@@DrWeselcouch it's up today but I'm extremely bad at making videos And the video quality is bad And by bad I mean BBBBB B. B BBBB B. B BBBB A A. A A. A. A A. A A. A DDDD D. D D. D D. D DDDD TOO BAD Humanly un-veiwable I don't know why in still making videos
Oh yes I am always in the mood for some trig sub
using this an hour before my final, legendary stuff here
did it help?
@@moabdul- yea i got all my theory problems right, i take computational so it wasn’t as bad, but really good for studying
@@jollux8035 sounds good, thanks man
Its the moustache!!! Thats his secret for being good at math
Amazing explanation ❤
I think there is another way to prove without the postulate let n!(n+2)^2=x^2 n! is perfect square n!=1*2*3..... make two groups of number one for primes from 1 to n and another from prim factorization of the non prime terms set one will be (p1,p2...pn) set two will be (y1,y2....yv) for x! having non promes other than one aka x greater than 3 yv is greater than pn for x! to be perfect square the product of all elements in the 2 sets should be like (p1*p2^h*p3^j......)^2 as p1 p2 p3 are just some primes and j and h are some random variables but this means x!=p1^2*p2^2h........ so there has to be odd number of a prime in set 2 for each prime in set1 but pn is greater than yv so there doesnot exist x!=n^2 for x greater than2 and you can check other cases for x smaller than or equal 3
I used this to make gravity in my Minecraft clone match Minecraft's. Using 9.8m/s feels like low gravity because of the voxel size
Very cool!
how did you get d(theta) to equal that? did you find the derivative of theta and then just rearrange the equation algebraically?
That is pretty much what he did, leibniz notation lets you treat them as fractions to an extent so he found dx dtheta and rearranged it. Also very nicely works out our jacobian
@@ComputerJunkie ohhhh thanks
you can also count the number of block that you needed to make the circle lol
But that's boring!
I'm currently making a video about math in minecraft, i searched for math & minecraft on youtube and i found your channel, it's really cool. I'll post the video on another channel that i have but i'll translate it to english. Why did you stop doing math in minecraft videos?
@@brinaxxx2316 Unfortunately I got busy with other things. That's awesome that you're making a math and Minecraft video. Please let me know when it's uploaded :)
@@DrWeselcouch i'll do, but it'll be in french =)
Thank you very much❤
how did you get 4.08 ?
This is amazing
banger video thank you so much
Helping students who self learn is a great deed! Thank u so much sir❤
Hi, could you explain how writing the elementary vector as a linear combination of the two given vectors helps us solve this? I am not understanding conceptually. Thanks!
Pascal's triangle can be constructed in the following way. The leftmost and rightmost entry of each row is 1. Every other entry is the sum of the two numbers over it. One thing to note: The sum of the entries in the zeroth row is 1, the sum of the entries in the first row is equal to 2, and in general, the sum of the entries in the ith row is 2 to the ith power. Another less obvious fact is that each entry counts the number of lattice paths from the top to that entry. Let's say for example... This number here is four (4), because there are four paths from the top to this entry.

Slow falling potion 🤨🤨
this is hard? lol
What about the air density estimated from the resistance in free falling?
That's an awesome question! I'll have to think about it. Let me know if you have any thoughts.
Hey how do you solve for g I've been trying to figure it out for hours
In which equation?
@@DrWeselcouchfor the distance equation with air resistance
@@jonathanrodriguez9849 You can't solve that with usual techniques from algebra. The best we can do is approximate the solution using a graphing calculator.
@@DrWeselcouch ohhhhh that makes a lot more sense. how did you do it with the graphing calculator. sorry for all the questions it’s for a school project
@@jonathanrodriguez9849 Move all of the terms to one side of the equation so you have (all the terms) = 0. Then graph the function and see where it crosses the x axis.
I have your brother as a teacher, i think you need to teach him how to play minecraft. We keep a tally on how many times he does something wrong in the game..please teach him dr…
Oh no! I hear that he's a big time noob!
@@DrWeselcouch Yes he is you should definitely teach him the laws of minecraft so next class he is ready
@@Meowzilla33 Keep me updated on his progress!
@@DrWeselcouch I will dr
Any updates??
You're back!
Oh yea!!!
Amazing title 😂
You are too kind!
I was really depressed this morning, and then things started getting a bit better, and then I clicked on this video to help me with my linear homework and I saw the "Simultaneous sip" and I was like: "Yeah, everything is gonna be alright."
Keep grinding brother man! 😤
But if you want to use L'Hopital's rule, the limit must be in fractional form which suggests that L'Hopital's rule can only be used for 0/0 or infinity/infinity Even if you get the other indeterminate forms, you have to write them in terms of 0/0 or infinity/infinity
go easy on us today 😭
LOL!
keep posting never stop ❤🎉
Awww thanks!
Weird, i was just randomly thinking about continued fractions this morning and then this pops up
The algorithm can read your mind.... 😱
Happens with me all the time
It's been so long, I hope you are doing well
Thanks! I'm happy to be back making videos :)
Great explanation sir!
Thank you! You are great!
Hello, welcome back.
😁
this measurement is credible, but it would be more credible if you wrote tp command as /tp @s ~ ~10000 ~ (~ is for relative coordinates)
cool 🌞
