I’m in college level Calculus (MTH 261), so I already know basic math etc., but it’s good to polish up on my skills because it can be difficult sometimes. I even relay on my calculator sometimes.😂
for younger kids i like to use the alligator metaphor-if the alligator is out of the water you need to cage him but if hes in the water you need a boat to get him
Use parenthesis and continue on with a “U” for union. For example, if x ≠ 3, then it would be (-♾️, 3) U (3, ♾️). This is saying you’ve included everything from negative to positive infinity except the 3 (due to the parenthesis around the 3, signifying you are not including the 3).
Brackets indicate that the value is included in the domain. Since infinity is theoretical and not an actual, finite number, you always use parenthesis with it. You would also use parenthesis around numbers not included in a domain (e.g. a hole in a graph, vertical asymptotes, and other values that do not fit within a domain)
Want to know how to express a solution in interval notation? Here are the basics you must know!
I cannot thank you enough! Watching your video has helped me to understand this better.
This definitely covers all the basics for interval notation
To infinite and beyond
You explained interval notation well
thanks dude, my brain was on fire!
These are very thorough examples
I’m learning interval notation in school. I like the examples you gave
Thanks for teaching me how to express a solution in interval notation!
This was beautiful omg 😢😢😢❤
Very helpful regarding the left-right rule when making the brackets
I struggled to understand this for mor than 10 yrs thanks you🙏🏿
Excellent style of teaching. I loved it! Thank you.
Oh ok so the parenthesis are used when the inequality symbol has either a greater than or less than sign
Bro thx i missed a week of school thx to you I understand
You explained it perfectly
That’s good to know about
Inequality/÷[ ] < > and to infinity and beyond
thank you so much
best vid yet!!!
This video is so much easier to understand than the way my professor teaches the class! W video!
It’s well explained. Helpful thanks
Great video thanks
Literally the best video omg
Thank you!!! A thousand times ❤❤❤
Interval notation seemed hard til I watched this
Thank you so so much man this came in clutch i had an exam
Thank you for the video. I was struggling with this part didn't know when to use the correct symbols you made it so clear.
this is fire bruh
This helped me in my pre calc quiz
Oh ! Infinity is a concept not an actual number ! I didn’t know ! So you always have to use a parenthesis ok.
Thank you Boss!
You are a life saver, thank you!!
Ok I see when a parenthesis or bracket should be used now
Oh the union of two sets is represented by a u that makes sense
Bro tysm you just saved my entire trimester
ngl interval notation is such a bitch to learn
Thanks for making me well understand the concept
How do we find the union and intersection of set and interval
e.g {1,2,4}u(3,5)?
Please look at the French way to write intervals. Much more simple, intuitive and consistent. Group of mathematicians called Nicolas Bourbaki.
Can you add a link to a vidoe for it?
Thank God for youtube teachers, im sitting in class so confused and i come here n i get it
👍
I want u to make another math notation series!! 😭👍🏻✨
thank you so much, you explained it so well!!
It's a good idea for me and the best teacher
Beautifully explained
thank you so much! you explained it perfectly and made it clear!
I see how you used interval notation to solve an inequality.
really helped !
i have an exam tmrw and this really saved me i swearr
Very helpful, thanks!
Lets gooo you can explain better than my math teacher

tysm
You’re a lifesaver! Thank you sm!! 🫶🏼
ok but why does 10 > 1/5t result in (-inf, 50)? why is infinity negative?
Ty it helped and you explained rly clearly God bless❤
ur a life saver thanks
Amazing
for younger kids i like to use the alligator metaphor-if the alligator is out of the water you need to cage him but if hes in the water you need a boat to get him
🙏 the math savior
thanks so muchh for this useful vid
like ah i understand now 🙃
❤
Gracias
School❌ TH-cam ✅
hope this helps me🙏
Shame its better explained here than in my college class
Is it possible to have (-3,-1) in interval b, or (-1,0) is possible fo interval b, because i didnt get a positive number to be with interval c
Thank youu
saved me
thank uuuu
thnx
how do i write ≠ into interval notation?
Use parenthesis and continue on with a “U” for union. For example, if x ≠ 3, then it would be (-♾️, 3) U (3, ♾️). This is saying you’ve included everything from negative to positive infinity except the 3 (due to the parenthesis around the 3, signifying you are not including the 3).
isn't infinity, ] ∞ or negative infinity, ]-∞ ? aren't these brackets [ ] called intervals brackets?
Brackets indicate that the value is included in the domain. Since infinity is theoretical and not an actual, finite number, you always use parenthesis with it. You would also use parenthesis around numbers not included in a domain (e.g. a hole in a graph, vertical asymptotes, and other values that do not fit within a domain)
I used this video to cheat on homework
I wouldn’t call it cheating 😁
You've learned nothing and you'll struggle further in math
preparing for finals 😂😂😂
Who else because of pre ib
Hi
Why do we need this crap anyway.. seems so dumb we could simplify this math so much ! No reason it should be so complicated
I have a exam in an hour, wish me luck i don’t know anything. 🫠
how did you do
@@minrain he failed and passed
Did you pass?
Me rn 💀
Same 😭😭😭
