3:16 why he choose number (y: 5),somebody can help me please
@@lucasisasi9759 he added 2 to x because 3 is greater than 2 we replace x with 2 giving us 5 in total.
His voice always calms me down during my pre-rest panic attack
I feel like 90% of the math I learn, I will never use other than to show people I failed at it
I have a friend studying aerospace engineering and she's studying certain physics and calculus she knows she's never going to use.
Its everywhere man
Like hell i wanna be a nurse,other than half lives, when am I gonna use quadratics lol
+ - • / is all the math you’ll need
right
i feel like all we really need to learn is the stuff in elementary. Addition, Subtraction, Multiplication, Division.
But after that i feel like people just got bored and said “Well we have to teach them something lol” and just threw some stuff in there. The stuff they have us learn isn’t able to be used. You’re not gonna put on your resume “I can do piecewise functions 😀”
after elementary, you should have some time to figure out what you want to be when you grow up, and dabble in a few things. Then you should go to school for the thing you want to be. Like if you wanna be an accountant, then you’d go to school for that, a doctor, a painter, a photographer, etc.
and learn the stuff you need for THAT thing.
_okay that’s the end of my Ted Talk thank you_
@@user-oo5xy3ee8o posted this 10 months ago and I still dont know how the fuck to do it
True dat
After 2 weeks of struggling with this, I am watching this the night before my test...and in just 11 minutes, everything made sense to me
2 weeks?? Bro my freaking teacher got through this in 4 days. Day 1 is learning it. Day 2 is a worksheet. Day 3 is review for test (on your own) and day 4 is test. This is so unfair
@@deffokay5879 well, we had multiple lessons on limits. I was basically behind on everything and my calc teacher loves to ramble on and on and get all theoretical, and my level of conscientiousness in extremely low 😖, that's why. Thankfully he's teaching it much better now. It all makes sense during class 🙂
@@deffokay5879 my teacher gives the homework, then explains the lesson the next day, then test the next. She is probably the worst teacher I’ve ever had but this video is the most helpful thing ever
@@deffokay5879 bro we had half a 50 minute period on it i am so fucked
Ha I wish mine was this way. We just learnt this a day ago and she’s already putting a test on it in front of us. She does this everytime we learn something. One day to learn it, one day to study, and then a test on something we barely understand.
i feel like im getting it at the same time not
Oof
One year later and I still don’t really get it :DD
@@abicados2386 lmao, I never got this eithet
tmr test, plz pray for me....organic chemistry tutor my last hope....
@@frankg2579 Good luck and God bless! You can do it! 🧡
i literally never talk in class and i pay attention but i still dont understand lmaoo
Matthew Field yooo same lmfaooo
Same, and I have a test on it tomorrow and literally no one in my class gets it
Matthew Field same
this shit makes zero sense
Same this is the one thing I don't understand
For the people who are still lost, what he is trying to do is combine the functions with the given parameters/limiters, whatever you want to call it. He is taking part of a function and graphing it on the same graph with each rule, and the first example itself explains it very well. Basically he graphs both graphs, but uses the x value limiters (x>/=0 and x
noob
I'm still lost lol
do you know the way
Lol same
Here
Same wth
he explains pretty bad its easier than that
You’re the best tutor on UA-cam
God bless you and keep up the good work
I really like the Khan Academy as well. To be honest I think TOCT does a better job of really breaking it down into a way that I can understand. Except for this section, I'm not grasping it
Agreed
me crying cause i still don’t know how to graph piecewise functions
hi Emily
That moment when you understand it just fine but still can't do it for some reason...
Me right now
literally!!! it's so annoying. like i get it in class but when i do seatworks im so lost
me rn
RIGHT!
That's it. I'm failing math and I'm a piece of disappointing trash.
Goodluck haha
Sir Sykes don’t give up, keep going
no ur not lol, literally everyone is bad at math. my mom, who is a pharmacist, is bad at math. you will get it eventually. its easy but has many factors
I used to say that i was bad at math. I used to fail tests like a champ and offer petty excuses. Until one year I made a commitment to myself that i would try to get an A. It was hard and the grading policies were tough but I realized that the only reason why i was bad at math was because I simply did not care at all about the class. I was lazy and did not want to try. I always believed i could not do good and that was the problem. I didn't pay attention in class or even care to listen to the teacher so I was constantly confused about the homework. It didn't help that i had not been paying proper attention in math for the past couple years as well. When i finally realized that this was the reason why i was bad at math and i began to understand how school worked then my test scores skyrocketed. Of course having a good teacher and you tube videos like this helped a lot but i was the one who was paying attention in class and doing the HW. I ended up with a B overall in the class and was very close to an A. So never say that you are bad at math or that you are garbage because i can assure you that you aren't. You simply need to get in the mindset to succeed and then work your butt off. You will face many difficulties as you try to improve in math but these difficulties will teach you many things and give you the skills that you need to succeed in other subjects . trust me. All you need to do is put forth the effort, start paying attention, and stop making excuses/being lazy. this was my experience. I hope you learned something.
Bro this school stuff doesn’t define you. You don’t need to get good grades to be successful. Keep ya grinding and keep ya head up
tutor: take your time graphing step by step and you should be fine. It's not that difficult
me: still gets it wrong
sarai mejia lmao
Relate🤣🤣
pov: you have a test in 2 hours and you're just now studying for it
I’m in a study hall without headphones rn so I’m studying with subtitles
@@masonharvey6149 not same externally but same internally if that makes sense ,Iam also using the subtitles
Yup
the night before but yes
ME RN
wow this is so helpful, much more than my college preCal's textbook. Textbooks are written professionally and they don't include tips or easy-to-follow steps, but you make learning math really interesting! thanks so much and i'm also looking forward to purchasing some of your merchandises!
I cannot thank you enough for these incredible tutorials I just started pre calc and you are a life saver
piecewise functions are the death of me😭😭 i asked my teacher for help after class today and he was like range is very difficult to find💀💀 so i had my twin brother who’s in calculus to help me. But this video helped me understand even more so thank you!
gave you the 69th like, congrats😃
For the people who are still confused after this video. I suggest watching other (youtube channel)videos related to this topic.
Based on my experience i watch 10 youtube vids (different youtubers) in order to grasp the concept and every youtuber explain their idea about the concept of piecewise function graphing.
For me after watching different vids. I come to conclusion that there is different ways to graph this piecewise function and our tutor in this channel use different method in every problem (thats the confusion comes)but if you can find a comfortable way to graph, stick to it.
Ok, imma do it
thank u broskie
Basically.. you'll need to know graphs of different functions, inequalities and set theory and
ahhhckk thank u for ur comment, that's whyyyyy
Why do I have to know this!
Best question
@StevenMora you don't
It just teaches you the type of critical thinking you need to learn actual math that you do need to know
@@sageofintellect6437 I learned that kind of critical thinking a million times before in middle school. I don't need to learn how to do critical thinking over and over and over and over again.
@@j.s.2958 Yes you do.
@@DanaLea57 no da fuk u dont, this is a pointless waste of time
My teacher could’ve just played this video LMAO
then your teacher isn't doing their job
One again Thank you very much. Math is a practical thing to me ,like cooking ,you really help simplify the 2 page notes they give us in class, and just simply show us "which is what" and what is being requested❤😊
This was so helpful, I learned this months ago but this was the perfect way to refresh my memory.
THANKYOU. MY TEACHER WASNT EXPLAINING IT AT ALL. YOURE A LIFESAVER
Love this! Great intro. Guys if your still confused, just do a ton of practice problems and have Photomath show you how to get the answers when you’re stuck.
It’s complicated f*s💔
Finally! I’ve been struggling with this since our school uses Aleks, but it doesn’t explain this well enough.
This videos makes sense for me, i even can understand what he said, incredible.
MR. organic Chemistry Tutor, thank you for Graphing Piecewise Functions. These functions are linear, quadratic, rational, radical and constants. The TI-83/84 Calculator is also helpful for Graphing Piecewise Functions.
you're an amazing tutor btw! You made math a little easier for me... Just hope our teacher will too >~
Professor's voice calms me down and opens my brain to understand. The best therapy ever for my math trauma experience.😂😂😂❤
omg this was so helpful!! exactly what i needed!!
I watched only a min of this video and got it right away. MANY THANKS!!
Thank you so much I've learn weeks worth of work in 12 min
My homework is like this but 10x more complicated
Can you please give reasons as to why you take certain steps?
Like why you picked the the positive side for when y=5
Thank you for this. It’s helped me a lot
Thank you I’m in an accelerated class we go over the concept once and test at the end of the week. Big help. 🙌😌
taking math classes online that barely give detailed help or explanation and the teachers almost always on break is recipe for disaster...until organic chemistry tutor videos exists
you fr carried me in my online chem and pre calc classes thank you :)
BRO, YOU ARE A LEGEND, KEEP UP :)))
A math tutorial with a clear voiceover!
Thanks. This video really helped me learning Algebra 2.
Your lecture feels like your re walking along with me in my brains!!! Thank you so so so so much😢
literally the best channel
This helped me a lot on todays pre-calc quiz, I missed the first lecture and missed out on this, but thanks to your video I was able to understand the concept and solve the problems in my quiz. I am genuinely grateful. Thank you very much.
you doin this in pre calc! 😭Why I have to do this in Algebra 1
Good luck to everyone in finals!!!!
Thanks! :)
Wow, thanks a lot bro u made things easier with that hyperbola example in between. Daya dankie ones again and keep up the good work hey
You, sir, are a life saver 🙌 ❤
I'm so surprised that I understood any of this. Thank a lot!
Thank you this really helped clear things up for me
This was so helpful
Thank you very much😭❣
I have a quiz on this stupid tmr and I'm still lost lmao
EDIT: I got 48% on the quiz lmao my friend got 16% and that’s what I have in class rn 😢
Same, I already know I'm going to fail it. I missed the lesson in class and the other kids said that the notes wouldn't help anyway when I asked if they knew how to do it😰😢
Sara Field I failed it lmao and my test is coming up next week so rip🌚
ppp.ingping_ and what did you get on the test??
@@caleblopez9970 yo their test was 8 months ago I don't think they remember LMAO
@@caleblopez9970 Aye bro I have a test tomorrow I'll let you know how that goes if that'll make you feel any better haha.
I dont get it👳
Ok piecewise functions are functions that consist of multiple functions on a graph and you will be given an inequality and you graph or subtitute
thank you so much i literally had no clue what was happening in class, and you just helped me so much because i have a quiz tm
Thank you from the bottom of my soul for this fast video!!!! Geesh
very helpful! thank you
I understand it better now! You’re a life saver TwT
THIS IS JUST AWESOME
Super helpful!!
Thanks for the wonderful explanation! :)
Thanks man. Keep it up
idk what id do without these videos
THANK YOU SO MUCH WITHIN 1:47 YOU TAUGHT ME MORE THAN MY TEACHER
how is it that you explain it so much better than my dc college algebra teacher ever does.
You have saved me from a great deal of pain , thank you sir
Thank you very much mr.... I've really been helped..🙏🙏
Thanks, brother!
Man this guy's a Multi talented he knows every single subject 🔥
this was really helpful
Tnx so much
Understanding this has never been easy
helped me a lot especially under isolation
srsly, thank you i might be able to answer smth at our test tomorrow
You need to compare all the math equations he did so you can understand how he did it. That’s how I somehow managed to understand his lesson.
this
just saved my booty, thanks man you the best
Don’t know where to put it . I really appreciate your playlists . If you’d drop a linear algebra ting would be gass .
thank you very much for this lesson, your explanations are very helpful!
It all makes sense now even after 1:30 in
I was gone when my teacher was teaching this so I needed to see this❤
Literally watched this for 2 hours straight, I finally get it lads🎉
wait why -2 squared is -4??? Its actually positive right????
bilah These two are different -(2)^2 and (-2)^2 since it didn’t include a parenthesis im pretty sure he assumed it was -(2)^2
XmasCarol true that
He correct
-2 squared is 4 not -4
Wait where did that -2 come from???? Pls help me
This was so helpful
Youve been my savior for yrs but for the first time im lost 😭
Watching this 2 hours before my test and hopefully I'll do good 👍
dam i had no clue but NOW i can do it. so that pretty POG thanks mate very god vid keep it up
👏🔥thank you so much, now I can go n face fourier series
I like how in depth you go, dipping into pre-calc to make sure everybody can follow. Even though most of these early videos are a review for me they help a ton reinforcing the ideas as I continue with my studies. Great work, I find your content more helpful than Kahn (not hating his style just doesn't jive with me very well)
“Graph it step-by-step, it’s not that difficult.”
Me, repeating PreCalc 1 and feeling attacked: 🥴 lmao
You are a bloody legend
Thank you so much
Yur videos areso helpful to somone like me who's just starting calculas 101
Kurtisha Charlery this is alg. 2 dipdick
u wish it comes back to haunt u in pre calc
@@fanwee5048 didn't say it wasn't . Just saying that this is the one of the first things you do in calculas 101 n this a helpful video. Smh
@@l0lgirl675 yep😭
Dafuq what do you mean, I’m doing this in 7th grade
Me at 0:00: I'm ready to learn!!
Me at 11:58: whaaaa????
You save my life! Thanks for your awesome videos. You explain better than my professor!
Very helpful video
Makes it easier if you make a x,y table and plot your points to stay organized.
Thank you!
very much helpful.
Thank you so much sir
Thank you very much
i finally get it ,thx sir
i started laughing when he said i take that back lmao
Using this for my pre-calc course and I like his voice, he reminds me so much of Mark Walberg talking. Same accent maybe? But its a good tutorial, Thanks!
shouldn't the x value of the square root function be at y=0 instead of 1 , like the parabola in the question before ?
how is a guy on youtube teaching better than my 9th grade math teacher
