Cross product(Vector Product) • The solution of a vector product AxB is a vector in a direction that is perpendicular to the two vectors A and B. (Right hand rule) • A X B = -B X A • [A XB] = AB sin (theta) • ixj =-jxi = k • jxk = -kxj = i • kxi = -ixk = j • ixi = jxj = kxk = 0
A x B = (Axi+ Ayj + Azk) x (Bxi+ Byj+ Bzk) = (Ay Bz - Az By )i = (AzBx - AxBz) j = (AX BY - AYBX) K
Determinate method (Ay Bz - Az By )i + (AzBx - AxBz) j + (AX BY - AYBX) k
