Orthogonal and OrthoNormal Vectors

Orthogonal and OrthoNormal Vectors : When the dot product of two vectors are zero , we say it as orthogonal vectors. If the vectors are normalised to a value 1, the these same orthogonal vectors are called OrthoNormal vectors. mathematically,

• any orthonormal set is orthogonal but reverse is not true.
• any orthogonal set corresponds to a unique orthonormal set but an orthonormal set may correspond to different orthogonal sets.
