*The cross product is defined in three dimensional space and it is denoted by axb.
*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.
*In CROSSPRODUCT (a,b), a and b are any two positive real numbers.
*We can calculate the Cross Product this way:<math>a×b</math> =
*We can calculate the Cross Product this way:
*<math>a X b</math> = <math>\mid a\mid</math>.<math> \mid b\mid</math><math> sin(\theta) n</math>
*<math>\mid a\mid</math> is the magnitude (length) of vector a
*<math>\mid a\mid</math> is the magnitude (length) of vector a
*<math>\mid b</math> is the magnitude (length) of vector b
*<math>\mid b</math> is the magnitude (length) of vector b
*<math>\theta</math> is the angle between a and b
*<math>\theta</math> is the angle between a and b
*n is the unit vector at right angles to both a and b
*<math>n</math> is the unit vector at right angles to both a and b.
==Examples==
#CROSSPRODUCT([2,7,8],[3,9,5]) =-37 14 -3
#CROSSPRODUCT([3,8,-2],[10,6,-5]) = -28 -5 -62
#CROSSPRODUCT([5.2,9.1,-4],[4,6,8]) = 96.8 -57.6 -5.199999999999996
