Exactly same question has been asked two years back. Here a answer from a moderator.

The public key is calculated by taking the generator point G and performing elliptic curve point multiplication on it with the private key. Given private key d and generator G, you do d * G. The process for elliptic curve point multiplication is detailed on wikipedia. The curve parameters are the ones for the secp256k1 curve which are defined here (section 2.4.1): http://www.secg.org/sec2-v2.pdf

Also below article could help you understand the process,

Hope you will get solution from above.

Hello, bitcointalkers! I have a problem with signing transaction in my wallet implementation. I can not understand how I can generate public key that based on my private key. I have private key that I generated randomly with 256 bits. I read in A.Antonopulos book that we can receive point on elliptic curve from private key. I received X and Y coordinates, What I need to do with it for transforming in single string row (traditional public key)?
