Please use that button with


to mark code. As above! Else all we get is a mess.

Again, i have no chance to understand the question.

  • We do not have the curve.
  • We have points that contain a z, which is an element of a polynomial ring. This ring has infinitely many elements. So the points do not live over a finite field.
  • Please give a reference to the curve, where is its equation? Where does the point $(x,y)$ come from?
  • You have implemented an algorithm for point addition and multiplication again and again. OK. Here we will use the one provided by sage. This information is misleading.
  • What does it mean i want to compute line equation of elliptic curve using above x and y in terms of z? Which "Line equation"?
  • How does the error arise? Give the code!
