What is a Unit Normal Vector?

Understanding the unit normal vector is essential in fields like Physics and engineering. A unit normal vector is a vector that is perpendicular to a surface or a curve at a given point, and its length is one unit. This vector plays a significant role in Calculus, particularly in multiple-variable calculus and vector calculus. It helps in simplifying many calculations related to surfaces and curves.
