    I like what I see here. Your presentation or rather the setting of your presentation is top-notch and matches the level of American teachers on TH-cam. Great job sir! I'm impressed

    Thank You sir how do we find a ratio of a geometric series :1/81-1/54+......?

    • @MlungisiNkosi
      @MlungisiNkosi  2 ปีที่แล้ว

      The same way you would any other ratio T2/T1

    Sir how do you solve for exponent x using log😭I'm used to the simpler way of solving an exponent

    • @MlungisiNkosi
      @MlungisiNkosi  2 ปีที่แล้ว +1

      You're most welcome to use it... I used logs for those who don't find the other way simple.

    hi sir i just wanted to say it does not make a difference in you answer if you use the different formula based on wether you r value is greater or smaller than 1, you can test it and your answer will come out the same if im not mistaken

    • @Envyius
      @Envyius 2 ปีที่แล้ว +1

      this is not with regard to infinite series

    • @MlungisiNkosi
      @MlungisiNkosi  2 ปีที่แล้ว

      You’re absolutely correct. And that’s why you’re given only one

    Good afternoon. I just realized something! In each and every lesson when we are about to calculate, you tell us that you need to download an emulator (I think it's a digital calculator). Do you always forget to download it or u remember when you teaching😂😂? Anyway, I think u should FINALLY download it...😂😂

    Is this not a formula for geometric series ? Seems like you wrote a geometric sequence and used the formula of a series( on your first example ) I stand to be corrected
