-As well as the affine coordinates, a point can alternatively be

-Jacobian projective coordinates are expressed as three values
-.Fa x ,
-.Fa y ,

-.Fa z .
-Working in this coordinate system provides more efficient point

-A mapping exists between Jacobian projective coordinates and affine

-A Jacobian projective coordinate

-Conversion to Jacobian projective from affine coordinates is simple.
