when modulus is on both sides instead of squaring both sides is it not possible to just make the whole of one side negative to find one value and then do both sides as positive to find the second value ? You get the same answer as squaring and it is much faster
If you’ve done linear graphing, you’ll notice that in every equation, you can find the y-intercept, or in most equations. For example: y = 3x + 3 That ‘+ 3’ at the end of the equation is the y-intercept, right? To work out the x-intercept, we make y equal to 0, and solve the equation from there; x-intercept in y = 3x + 3 would be, 0 (make y=0) = 3x + 3 then, subtract 3 from both sides (to get rid of the ‘+ 3’ of course😁), and you’re left with -3 = 3x And finally, x = -1 So, the x-intercept in y = 3x + 3 would be (-1, 0) on the graph! In summary, this youtuber has used the x & y-intercept method to draw the linear line; (sorry for the use of slashes instead of ABS bracketsㅠㅡㅠ) y = /2x + 1/ can be solved using the methods at 3:57 like this Hopefully I was able to answer your question...
Not to sound rude but what is the purpose for having a Modulus function? What application would this be used for, both in maths and the physical world?
If u put it that way, I mean physical world there really isn’t any function that’s gonna help u LOL. Except for add,sub,multi,div functions there really is no use of it funny but ur future depends on it
Super straight forward and covered everything i needed. May god bless you 💙💙
super clear and concise explaination, Thank you!
It really helped me for my test tomorrow. Thank you so much!!!!
You dropped this 👑
U r true math genius
God bless you
You've helped me big time, lad. Thanks!
Thank you for this video! It helped me clear up my mistakes. Very useful
Wonderful explanation!! You covered everything.... I think it'll help me with my competition
I'm most grateful, keep on the good work, God bless you.
Clear and well explained. Thanks a lot
Your explanation is fantastic. Thank you very much
you are actually so fantastic tysm
For solving the equations it's like solving a quadratic with +ve & -ve solutions but you don't square root anything.

That's a property of modulus
If |x| = |y|
then, x = y and x = -y.
I did that in a test I failed
Thank you so much
Absolute value= modulus
Thank you so much!! Keep up the great videos.
This was really helpful thanks so much
Legend 😅
this was so easy,, thank youu
thank you!
Love from India
🎉
clear explanations
Good stuff. Thank you 👍🔥
thanks for this vid very helpful
is this for the new spec or old one. The content looks lyk the one for the new spec because im doing it but i dont know.
thx very much
Thanks a lot
Don't you have to find turning point for quadratic graphs and make that positive too?
Good Video
* very good video
this is very clear, thank you!
When did this stop being called absolute value?
I like the accent
which app do you use to write like that? I want to make RUclips videos too
3:57 How do you know y =1 and x=0 on

@@mingyu1211 What a way to explain it. Masterfully done.

Just to pass the time....skip it bro

16:53 why is it squared?
Good vid but boost ur fps man
Wth! 2hrs ago......altrenative comment dont be like cyberpunk.
@@tutuseleshi7640 what?
Your explanation is very clear but in the conclusion you sure made a mistake
It was supposed to be +2 and-4 not-2 and-4
Your discussion on modulus graphs should have been longer.
it's free knowledge
hi, you made an error at 10:24 the x coords are supposed to be 3,-2 instead of what you put and y should be -6
How is it an error. He has done it right
@koukhao sry mate ur wrong
dw i see why you think it is that though, you have to switch the signs to get the coordinates
@@drgnyt7487 thank you for the explanation

Is this gcse or a level?
This one is a level
Maths Genie Oh okay thank u sir
17:35 did he just say minor sex?😳😳😳
