I know they're talking about secp256k1, that's what I hinted to, but I wanted to hear it from them 
I find it weird to start off a question like that, especially if you just say it's a 'math calculation problem' and don't introduce anything, just put out some formulas out there. Seems like the person is putting in the minimal amount of effort, but expects someone to put in their time (actually more time than needed due to unclear question) to help them.
This has been a common theme with OP's topics for months. They first assume there is a relationship between private keys, nonces, hashes, etc. Then OP asks others to provide a solution to compute private key using the ECDSA equation. Then you see OP is asking how they can parse the blockchain and finally you see OP is selling some script that computes private keys!
