Answer:
If a = <a1 , a2 , a3> and b = <b1 , b2 , b3 >, then the cross product of a and b is the vector, a x b = <a2b3 – a3b2 ,a3b1 – a1b3 ,a1b2 – a2b1> = (a2b3 – a3b2 )i + (a3b1 – a1b3 )j + (a1b2 – a2b1 )k
Explanation:
Note the result is a vector and NOT a scalar value. For this reason, it is also called the vector product. To make this definition easer to remember, we usually use determinants to calculate the cross product.
When you take the cross product of two vectors a and b, The resultant vector, (a x b), is orthogonal to BOTH a and b. We can use the right hand rule to determine the direction of a x b
