  1. yeh they do... u know I did that but I didnt get the same answers and now I understand why.. thanks alot!!
  2. yep, thus 2x-2y = 0
    Then how do I find the coordinates as I can only simplify to x=y
  3. ok, a curve is defined implicitly
    x^2 -2xy+4y^2 =12
    a) find dy/dx and where the tangents to the curve are parallel to the x - axis ...
    dy/dx = (2x-2y)/ (2x-8y)
  4. Ok, last q of the day ...
    If u have worked out dy/dx and then it says find the coordinated for when the curve is parallel to the x axis at this point the numerator will = 0 .. right ... and if it said parallel to the y- axis the denominator would be = to 0 ... is that correct???
  5. gracias
  6. cool
  7. Hey bro? I see you help a lot in the maths forum! That's really good of you
