Can you provide more details (what is secp256k1, for example), explain what you've tried, and tell us how this relates to SageMath?

The order of secp256k1 is odd (see here), and so there are no points of even order, including order 2. The only order-1 point is the (additive) identity element (0 : 1 : 0).

I'm not sure what are "first" and "second" elements you refer to.
