Prime numbers have many applications. For example, in cryptography. The RSA algorithm for public-key cryptography uses large prime numbers for generating keys. Quote: The RSA algorithm works as follows: take two large primes, p and q, and compute their product n = pq; n is called the modulus. Choose a number, e, less than n [...]

Normalizing a vector can derive the direction of the vector in 2D or 3D space. A normalized vector is also known as a unit vector. We’re going to normalize and calculate the angles of a 2D vector at position (5,5) and a 3D vector at position (5,5,5). This can come in very handy when, for [...]
