    Thanks for actually breaking down why the values are the way they are- it helps those who will only remember stuff if they understand why something Is the way it is. Well done 👍🏽

    Thank you for explaining this topic. You have made this topic clearer. I would just like to know if the side measurements have a set number like 1 or 2? Thank you.

    • @TheGCSEMathsTutor
      @TheGCSEMathsTutor  2 роки тому

      No problem at all! For the side measurement I have used the smallest possible lengths, you can use any but you would then have to simplify the surds/fractions in the exact values!

    at 7:01 for the exact trig value for tan you got 1/ square root 3 but on the table it says sqaure root 3 / 3. Does that mean we rationalise the denominator ?
