Dot ProductScalar or Dot product(1) Scalar or Dot product of two vectors: If a and b are two non-zero vectors and θ be the angle between them, then their scalar product (or dot product) is denoted by a.b and is defined as the scalar |a||b| cos θ , where…

Cross ProductVector or Cross product(1) Vector product of two vectors: Let a, b be two non-zero, non-parallel vectors. Then a × b = |a||b| sin θ \(\hat { n }\), and a × b = |a||b| sin θ where θ is the angle between a and b, \(\hat { n }\) is a unit vect…
