    Malume on your domain kant it won't be x is element [-30 ; 150]😢 since it's shifted to the left

    Hi sir, is it possible to get the points of a trig graph that has transformations using the calculator's table mode? I've tried but I might be doing something wrong

    • @MlungisiNkosi
      @MlungisiNkosi  Год назад

      I find it tedious hence I always use the normal graph as a reference

  • @blue_spxrkls
    @blue_spxrkls 2 года назад +2

    uhmm i just wanted to ask whether would they give us a frequency of more than 3 ,as in like having to divide 90 into 4 or more equal parts maybe? i dont know if i make sense but yeah

    • @MlungisiNkosi

    • @HappyHiker-sc2hq
      @HappyHiker-sc2hq 2 месяца назад

      No it makes sense because you draw your graph with the vertical shift which was - 1 so 2-1=1 the equation which had the amplitude of 2 would've remained the same if there were no V. S
