u Cross Product [OPTN]-[MAT/VCT]-[CrossP]
Example To determine the cross product of the two vectors below
Vct A = [ 1 2 ] Vct B = [ 3 4 ]
K2(MAT/VCT)6(g)6(g)
3(CrossP( )1(Vct)av(A),
1(Vct)al(B))w
u Angle Formed by Two Vectors [OPTN]-[MAT/VCT]-[Angle]
Example To determine the angle formed by two vectors
Vct A = [ 1 2 ] Vct B = [ 3 4 ]
K2(MAT/VCT)6(g)6(g)
4(Angle( )1(Vct)av(A),
1(Vct)al(B))w
u Unit Vector [OPTN]-[MAT/VCT]-[UnitV]
Example Determine the unit vector of the vector below
Vct A = [ 5 5 ]
K2(MAT/VCT)6(g)6(g)
5(UnitV( )1(Vct)av(A))w
u Vector Norm (Size) [OPTN]-[MAT/VCT]-[Norm]
Example To determine the vector norm (size)
Vct A = [ 1 3 ]
K2(MAT/VCT)6(g)6(g)6(g)
1(Norm( )6(g)6(g)6(g)
1(Vct)av(A))w
• You can use the “Norm” command to calculate the norm of a matrix.
