MR thanks you are doing a great job many benefits from your services and as i was doing g12 last year in march i got 41% and i started following your channel I ended up getting 84%(physics) kube useduze ngabe ngakuhlabel nenkomo😅
Sir , I can never thank you enough❤ I'm upgrading my physical science and maths and you really made me wonder why I didn't do better on metri because everytime I study with your videos I'm like 🤦♀️ haibo mos lento ilula. And yes I recommend you all the tiiime. I wanted to ask if you gonna be doing probability and financial maths anytime soon or sizazbona ?🙈
Hi sir, im a bit confused, once you find your x points for your P.O.I and your stationary points, in which equations do we substitute it in to find the corresponding y values
Mr Nkosi, for the second one. To substitute for the TP point I used (-2) and I got (16) and I felt like it made sense. Am I wrong for writing that as my turning point?
Anyways thank you sir when it came to calculas I would only write the first principle them leave the ret but this time😭😭😭im going to attempt everything thank you so much
41:10 sir was having a doctor strange moment there. I don’t know what was going on. I just used the quadratic equation and reversed my answer to get my brackets. A little cheat code I use😂😂
Hi, I also used synthetic division and got 0. Make sure to include placeholders for missing coefficients, meaning where a coefficient is missing in synthetic division put a 0.
Very helpful thanks a lot
Mara sir inflection at 28:56 mins is -6x + 6 not just -6x sir
Which makes it -6x +6 = 0
-6x = -6
x = -6/-6
x = 1
I also saw it too
Never mind he fixed it
Thank you so much
Very helpful😌🙏
I can't believe that I understood this in less than an hour!! Thank you so much Mr Mlu, you've just made Maths to be simple. bless!!!!!
It’s my pleasure. Thank you
Never have I ever enjoyed a Calculus lesson. Enter Mr Mlungisi Nkosi👏🏽👏🏽👏🏽. You Sir are heaven sent❤🔥
God bless you❤❤.... I wish I knew you starting from grade 10 ... know I am in grade 12 and because of you I understand everything
You’re most welcome

Wow congratulations… Ngicela leyonkomo uyibeke ngizoyilanda 😂
How?😳😳😳👏
@@MlungisiNkosi Nice ✅😎
Thank you so much Mr nkosi for this channel. It is really helpful . May God continue to bless you🥰
You’re welcome ☺️
Thank you for making cubic functions much more easier and understandable . Thank you so much Mr Nkosi .
The pleasure is all mine
Great lesson really enjoyed it 🥰Thank you SIR !!!!!!!!❤❤ it took a lot of discipline to watch it 😭🥲💔
😭I’m writing math tomorrow , and I understand thanks to your channel
You’re most welcome 🤗
Thank you Mr Nkosi for creating this channel it's really helping me a lot ❤️✨
The pleasure is all mine… 🙂
Isn’t the POI -6x +6
Therefore the points are (1;-2)

Thank you so much Nonhlanhla. Yes I’ve started recording probability and I will publish it in the coming day. Keep your eyes locked right here
This lesson was sooo helpful. Thank you🙏
You’re welcome ☺️
Thank you sir for Lungising this chapter🙏❤️❤️😀 needed this so bad.
Lol @ Lungising 😂
@@MlungisiNkosi 😂😂
You're a veryy good teacher sir , thank youu .
Thank you 😊
Hi sir, im a bit confused, once you find your x points for your P.O.I and your stationary points, in which equations do we substitute it in to find the corresponding y values
The original equation... f(x)
Thank you alot for your videos they really help us in improving🙏
Happy to hear that!
Thank you sir 🙏🙏 happy Sunday everyone fav place for the whole year 🙂
Thank you Racheal
Thank you so much sir you make things simple for real.❤🤝
My pleasure
thank you sir😭❤️
Aibo ! May God bless you Mr ❤
You’re welcome 🤗
You really helped me a lot yoohh😭Thank you Mr
You’re welcome ☺️
Mr Nkosi, for the second one. To substitute for the TP point I used (-2) and I got (16) and I felt like it made sense. Am I wrong for writing that as my turning point?
Sharp
What if I get 2 different factors ? How will I be able to choose the correct one
I really enjoyed the lesson thanks a lot
You're welcome
You are phenomenal Sir
Thank you so so much 🤗❤️
Very helpful sir. Best teacher ❤
You’re welcome
Anyways thank you sir when it came to calculas I would only write the first principle them leave the ret but this time😭😭😭im going to attempt everything thank you so much
You’re welcome ☺️
Sir if you get a chance❤please do past questions paper about cubic functions
I definitely will
@@MlungisiNkosi Pls Sir🙏
That was a good example.
Hi Sir, on part 28:42 how did you get 3x squared + 6x. please kindly assist
Please check the lessons before this one on the rules of differentiation
Hi sir!!! Just wanted to know if all the math videos will be out before the may rewrite? ❤️
I don’t think so… I almost worked myself to death trying to do that.
But Mr how do we factories the equation that does not have bx squared
Watch the next video. You will see
41:10 sir was having a doctor strange moment there. I don’t know what was going on. I just used the quadratic equation and reversed my answer to get my brackets. A little cheat code I use😂😂
Same🤣🤣
Thx for being a life saver 😭😭
The pleasure is all mine
Great lesson 🙃🇿🇦
Thank you 🤗
Sir please do a video on graph interpretation questions that involve for which x-values 😭😭😭
Most definitely Phindi. I have started recording probability now… I’ll get to those at a later stage.
Thank you sir. I didn't understand this in class but now I've just mastered it.❤🔥🔥
Awesome 👏🏾
Enjoyed the lesson 😊
You’re welcome
The best
GOD BLESS YOU🙏
Thank you so so soooooo much😭😭
Hi sir may I please have a video of how you factorise on the x intercept, thank you😇
Ok, noted..
sir can you please do an example if they give you a QUADRATIC FUNCTION BUT THEY WANT YOU TO DRAW A CUBIC FUNCTION
I actually did that in my class this morning. I will look at that very soon…
thank you sir...
21:50 when using synthetic division
i keep on getting X^2-4x+8 😢😭
Hi, I also used synthetic division and got 0. Make sure to include placeholders for missing coefficients, meaning where a coefficient is missing in synthetic division put a 0.
Thank u soo much sir💙
You are most welcome 🤗
Thank you sir
for some reason I find it easier when you write on paper.
I hear you… but ke, we also have to move ahead with the times
Sir at which school are you teaching ?😊
Sir isn't the point of inflection-6x +6
Since the first derivative was -3x^2 + 6x
So we remove the x and we left with the 6
😭oh sorry I saw that you fixed it after
Thank you
@@robertmphaka5208 awesome thank you 😊
You are very good.I hope you work for RUclips
Let’s get those numbers up…
I got an answer of 6x from the activity given to us, is it correct?
Correct…
Point inflection please check it
❤❤
My pleasure
sir how do we find concave down?🙂
Use the inflection point
Hallo sir, I keep on getting ×^2-4×-8
SIR I GOT A LIL CONFUSED ON INFLATION I GOT MY ANSWER AS 1
GOT IT NOW
I’m glad you got it
Sir sawubona 😀
Sawubona Charlotte 😊
Also Mr there's physics part in culculus 😭😭😭😭
I’ll be publishing that during the course of the week.
Hello
I dont understand the point of inflection.
What do you not understand about it?
Good day sir you have made a mistake some where
Where is somewhere?
In tbks questions 1b the sings 4 musf be negative and 2 positive
🥲❤everyday I thank God for you... I understood in less than an hour
You’re most welcome
