The cross product of two vectors a and b is defined only in three-dimensional space and is denoted by a b. In physics sometimes the notation a b is used though this is avoided in mathematics to avoid confusion with the exterior product. For computations we will want a formula in terms of the components of vectors. We start by using the geometric definition to compute the cross product of the standard unit vectors. Cross product of unit vectors. Let vci vcj and vck be the standard unit vectors in R3. (We define the cross product only in three dimensions. The dot product is also a scalar in this sense given by the formula independent of the coordinate system. Examples include Mechanical work is the dot product of force and displacement vectors Power is the dot product of force and velocity. Generalizations Complex vectors

This formula is not as difficult to remember as it might at first appear to be. First the terms alternate in sign and notice that the 2x2 is missing the column below the standard basis vector that multiplies it as well as the row of standard basis vectors. Although this formula is nice for understanding the properties of the dot product a formula for the dot product in terms of vector components would make it easier to calculate the dot product between two given vectors. Vector product- Cross Product of Two Vectors. We know that there are two ways of multiplying vectors. (i) Dot product of vectors (also known as Scalar product) (ii) Cross product of vectors (also known as Vector product). In the upcoming discussion we will focus on Vector product i.e. the cross product of vectors. Cross Product

This physics video tutorial explains how to find the cross product of two vectors using matrices and determinants and how to confirm your answer using the dot product formula. This video contains Where is the angle between vectors veca and vecb. This formula gives a clear picture on the properties of the dot product a formula for the dot product in terms of vector components would make it easier to calculate the dot product between two given vectors.
