# how to get rank of elliptic curve of QuadraticField

I try two examples,even elliptic curve of Q cannot run:

```
E = EllipticCurve([0,0,0,0,2332])
show(E)
K1.<a> = QuadraticField(-3)
E1 = EllipticCurve(K1,[0,0,0,0,2332]);show(E1);
E.rank()
E1.rank()
E = EllipticCurve([0,0,0,-15,22])
show(E)
K1.<a> = QuadraticField(3)
E1 = EllipticCurve(K1,[0,0,0,-15,22]);show(E1)
E.torsion_points()
E1.torsion_points()
E.rank()
E1.rank()
```
