An other algebraic
operation which we intend to discuss regarding vectors is their product We may
recall that product of two numbers is a number, product of two matrices is again a
matrix But in case of functions, we may multiply them in two ways, namely,
multiplication of two functions pointwise and composition of two functions Similarly,
multiplication of two vectors is also defined in two ways, namely, scalar (or dot)
product where the result is a scalar, and vector (or cross) product where the
result is a vector
