# Quiz 15 #### Which of the following are parameters required to define an elliptic curve? * [x] Coefficients a and b * [x] Prime modulus p * [x] Generator point G * [x] Order of the group q * [ ] Hash function h(m) * [ ] Ephemeral key k **Notes to Learners** When working with elliptic curves, certain parameters must be clearly defined: a, b (Coefficients that define the elliptic curve equation: y² = x³ + ax + b), p (Prime modulus that defines the finite field), G (Generator point that generates the cyclic group of points on the curve), q (Order of the group generated by G). To learn more about it, you can follow the course [Elliptic Curve Digital Signature Algorithm (ECDSA)](https://bsvblockchain.360learning.com/course/play/68dcfb7db22b823a03f88909) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://hub.bsvblockchain.org/higher-learning/bsv-academy/bitcoin-primitives-digital-signatures/quiz/quiz-15.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
