*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:

*We can calculate the Cross Product this way:

*<math>a\chi b</math> = <math>\mid a\mid</math>.<math> \mid b\mid</math><math> sin(\theta) n</math>

*<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

*n is the unit vector at right angles to both a and b
