CROSSPRODUCT (a,b)

This function shows the Cross product of two numbers.
Cross product is also called Vector product.
The cross product is defined in three dimensional space and it is denoted by axb.
In CROSSPRODUCT (a,b), a and b are any two positive real numbers.
We can calculate the Cross Product this way:
$aXb$ = $\mid a\mid$ . $\mid b\mid$ $sin(\theta )n$
$\mid a\mid$ is the magnitude (length) of vector a
$\mid b$ is the magnitude (length) of vector b
$\theta$ is the angle between a and b
n is the unit vector at right angles to both a and b
