Vector Product of Vectors

Vector Product of Vectors

a=x1i+y1j+z1k
b=x2i+y2j+z2k
c a c b
c = a × b = | i j k x 1 y 1 z 1 x 2 y 2 z 2 |
c = ( y 1 z 2 z 1 y 2 ) i + ( z 1 x 2 x 1 z 2 ) j + ( x 1 y 2 y 1 x 2 ) k
| c | = | a | · | b | · s i n α

The result of vector product, vector c, has a length that is equal with the area of parallelogram between vecrors a and b (pink area).

Keywords: multiplication of vectors, vector product
