GEO satellites: Inclination vector evolution

What is cross vector? In this video, Dr. Walter Lewin presents the concept of cross product of two vectors. The cross product, also known as the vector product, is a binary operation on two vectors in three-dimensional space. It results in a vector that is perpendicular to both of the original vectors and is denoted by the symbol ×. The cross product is defined only in three-dimensional space and has many applications in mathematics, physics, engineering, and computer programming. In mathematics
