    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!

      ​@@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.

    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
      @MlungisiNkosi  2 года назад +11

      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.
