I was really confused on why you used the coordinates of AC instead of AB when you calculated the gradient of AB but I managed to fix it myself and by the way I'm a month old subscriber and I'm glad to tell you that your Content is great help!Thank you Sir!

[@MlungisiNkosi]

Thank you Amo… I’m glad you’re able to bare with this old man even when he makes mistakes. Thank you so so much for joining us. I hope this channel really becomes a home for you

[@Mgijimiibhincakazi-rc2ww]

How did you work it out cause Im also confused

[@kagisoseer6706]

Distinction on Maths& Physics it's promising.... Thanks to You Sir

I normally skip adverts but for you uncle I will watch all of them no matter how long they are, so grateful for your content ,one day I will be rich and you will be one of the few teachers I will spoil!

[@MlungisiNkosi]

Wow… I can’t wait 🤩

[@user-my5rt6cl5p]

Thank you so much Mr Nkosi for boosting my confidence 😊

[@rach-tech6191]

sir, you use the coordinate of AC to find the gradient of AB,at the ALTITUDE diagram

[@MlungisiNkosi]

Thank you for making me aware. I hope it didn’t affect your understanding

[@naleditalib9175]

Sir I got lost on the altitude section ...for gradient of BT the inverse is -¾ or?

[@kikylinda5710]

@@MlungisiNkosi sir it changes the answer the equation is then supposed to be y=-3/4x+8.5

[@Oratilwe.x_]

😭I was lost thanks for your comment

[@siphesihledlomo8458]

​@@Oratilwe.x_The equation is still the same. It is just a matter of changing AB to AC. Correct co-ordinate substitution but wrong naming. He was supposed to name it a Gradient of AC not a Gradient of AB. Remember he was explaining the concept of Altitude using the concept of perpendicular lines. BT is perpendicular to AC, hence he had to find the Gradient of AC in order to find the Gradient of BT, then the equation of BT.

Thank u sir i was really strugling with this at school

[@_.tshiamo]

Good day sir, why did you use coordinates of C to calculate the gradient of AB ?

[@primrosepewa4017]

It's all appreciated thank you sir🙏💯

Hello to my best mathematic teacher ever🌼Is this video adequate for basic knowledge of analytic geometry or you also recommend me to watch the next video?

[@MlungisiNkosi]

Hi Fatima, And thank you for the awesome compliment. I do recommend that you watch the the next one as well

[@fatimaghasemi9452]

@@MlungisiNkosi thank you so much

[@sinakhokonkemyeza6660]

Hello Mr Nkosi can I please ask something let's say for example you got 67%for example for Physical Science and you studying in Varsity but you wanna improve this mark are you allowed to register to write in the upcoming final exams in November and also how will they allocate the mark if they do let you if you score lower than that do they give you the lower mark? Just wanna know cause one of my mates got that and they Wanna improve to try get bursaries in relation to Engineering and it's a tough field In terms of Math and Science.

[@MlungisiNkosi]

They can register but I highly doubt registration is still open. If it so happens that one gets a lower mark, they always consider the highest mark as the official one. But there’s no way you can get a lower mark with MlungisiNkosi as your plug… Not possible.

[@olwethungcepe-ri2xw]

You are absolutely the best teacher ❤You teach us step by step 🤌You don't assume that everyone knows it 🔥nah Thee Best !!!

[@MlungisiNkosi]

Wow, thank you!

[@siphiwemaseko1241]

Good lesson indeed sir Can i ask it is you're calculating on Y=MX+C it is possible for C to equal to a negetive number ?

[@MlungisiNkosi]

Yes that’s possible

[@nobahlemaneli8161]

It’s great lessons. Is it possible to download Sur

[@cwengacwera652]

So C is always positive?

[@Art_with.Tavonga]

Sir are we working with the gradient of AC or AB

[@lisandwandwa790]

Thank you sor lesson was superb

[@MlungisiNkosi]

My pleasure

[@oumamutshidzi97]

I'm still lost as to why we use AC to find the gradient for AB ?

[@MlungisiNkosi]

It was an error

Am writing maths this year but am. Not happy Am planning to rewrite it next year june Can u please don't leave this platform because I want to start studying in July for maths and physics so I can pass because with you am able to understand a lot of things but in my high school years I was blind I don't know what happened

[@sanadungaria8215]

Or a playlist of the whole topic analytical geometry? Or is this the only vid

[@MlungisiNkosi]

No it isn’t

I’m writing tomorrow now I feel like an ready for the test thanx sir❤️

Thank you

[@extratimecontent2531]

Is it safe to say the gradient of perpendicular lines are reciprocals ? And is the concept of understanding one on one or many to one functions relevant in this topic?

[@MlungisiNkosi]

Yes it is…

[@sanadungaria8215]

Sir do you have a vid of lesson in analytical geometry including circle?😭

[@MlungisiNkosi]

Yes, I will create a Playlist soon

good morning sir question you said we finding gradient for AB right why are we using the coordinates for AC 🤔😊

sir, for the gradient of BT shouldnt you use line AC?

[@MlungisiNkosi]

@@2kaay_946 you’re absolutely correct. Eish I get nervous when I record. You’ll see that I used the co-ordinates of AC but called it AB for some strange nervousness reason 😅

[@happinesscasmiro2569]

sir please do the intersaction of circles

[@MlungisiNkosi]

Great… I shall

[@jeanetterabotapi1562]

Sir you didn't include collinear points how do we calculate them

[@MlungisiNkosi]

Collinear points are point on the same straight line… Their gradients are equal

Hi at 17:47 why did u say that AB is perpendicular to BC

That was a mistake I think
