    This has taken me 6 years to get this far and to keep my site free. These will come at some point when I get time after doing Further maths tutorials next.

    Thank you for all your videos! They have been a great help, and it is evident how much time and effort you put into your videos; I wish my teachers put as much time and effort into teaching their students! However I was wondering if the numerical example would be up soon, I think it would be easier to follow this video/rules if there was a question to work through. Thank you again, and my grade in the summer will be all down to you!

    You devoted your life to this. Each video is an honourable achievement! I've learnt so much which I could not if these were not free. You're a brilliant teacher! Thank you.

    I have a question. Isn't Differentiation and taking logarithms similar in the sense that they both convert a non linear equation into a linear equation?

    • @ZAH33D
      @ZAH33D 11 หลายเดือนก่อน

      Pretty sure Differentiation converts it to a single quadratic equation. Might be wrong though since I'm stupid and replying to an 11 year old comment.

    when finding the y intercept when you put e^1.2 how did you get 3.3 ?

    • @ExamSolutions_Maths
      @ExamSolutions_Maths  9 ปีที่แล้ว +2

      MistD Use your calculator, e is a constant and is on the calculator.

  • @quosswimblik4489

    What if you had to find how to quickly calculate say the factorial exponent or the circular exponent or the circular log. Then you would either need some very long winded calculus to get anywhere or you could line up a vertical line with a curve where by the vertical line stretches the curve the bigger your value n. This new way of thinking about curvature could lead to a new degree of ability with a dynamic range of exponential types.

  • @ExamSolutions_Maths
    @ExamSolutions_Maths  11 ปีที่แล้ว +2

    I didn't. It was 1.2 and I made it up to demonstrate the example.

  • @lydiajones6183

    When reducing exponential, how come we plot lny and x, instead of lny and lnx

    • @jamesthomas6867
      @jamesthomas6867 4 ปีที่แล้ว +1

      Since x was the power in that case it went to the front of lnb meaning it was a constant separate from ln

  • @eleanort8347
    @eleanort8347 2 ปีที่แล้ว

    How do you know which to plot? That for the first it was lny against lnx and then lny against x?

    • @airmathstuition9
      @airmathstuition9 2 ปีที่แล้ว

      It depends on the power equation. After you've taken the log if both sides of the equation and then compared coefficients with y=mx+c, you'll know exactly whether to plot lny y vs x or lny vs lnx
