EllipticCurves :: isOnEllCurve(List,EllipticCurveW)

isOnEllCurve(List,EllipticCurveW) -- A method to check if a point is on an elliptic curve.

Synopsis

Description

Tells whether the point of projecive coordinates { L#0 : L#1 : L#2 } is on the elliptic curve E

i1 : E=ellCurve({1,2,3,4,6},GF(29))

o1 = Elliptic Curve defined by Y^2 + 1 XY + 3 Y = X^3 + 2 X^2 + 4 X + 6( over(GF 29 .))

o1 : EllipticCurveW
i2 : isOnEllCurve({1,5,1},E)

o2 = false
