    For the last question, why can you use the x and y coordinates of the original equation for the normal? How do you know that the point (1,-2) is on the normal line?

    • @1stClassMaths
      @1stClassMaths  4 месяца назад

      We are finding the normal at the point where x = 1
      This means both the normal and the curve will intersect at the point when x = 1
      Using the original curve's equation we find the y coordinate when x = 1 to be -2 so the point where they intersect is (1,-2). This means this point must both be on the curve and the normal. The same idea applies when you do tangents as well. You will often need to know the coordinates of a point on the normal/tangent and the easiest one to use is the one where it crosses the curve as they both have the same coordinate.

    For the last question why cant I find the equation of the tangent, and then find the equation of the normal from there

    • @1stClassMaths
      @1stClassMaths  Год назад +4

      Hi. You can do this yet but it is not necessary. You don't need the full equation of the tangent, only it's gradient. The y intercept for the tangent unfortunately doesn't help get the equation of the normal at all so you may as well skip it!
