adjective. noun. The definition of normal is regular, natural or staying with the general standard. An example of normal is a human temperature of 98.6. Normal is defined as the usual or the average. An example of normal is the general amount of goods that a company makes each year.
For example, the y-axis is normal to the curve y = x2 at the origin. However, normal may also refer to the magnitude of a vector. In particular, a set is called orthonormal (orthogonal plus normal) if it is an orthogonal set of unit vectors. As a result, use of the term normal to mean orthogonal is often avoided.The word normal also has a different meaning in probability and statistics. A vector space with a bilinear form generalizes the case of an inner product. When the bilinear form applied to two vectors results in zero, then they are orthogonal.The case of a pseudo-Euclidean plane uses the term hyperbolic orthogonality.he word normal also has a different meaning in probability and statistics.
