Have you learned general dimension determinants? Did it bother you? If you say yes to both questions, join me making determinants clear.

How vector rotates? Does it really need quaternions? In a few pages we will know how to do it, with and without quaternions.

Have you wondered how elliptic curve can be used to do cryptography? I surely did! In this series of articles we will explore about it. I’ll also tell what I know I don’t know yet.

Have you ever wonder how public key encryption and signature works? Or did you find its mathematics hard? Here’s my take understanding and explaining its beauty.

After vector products are introduced, books usually give a list of relations without proof. Let’s try them.
