Use the given vectors u, v, and w to find each expression.

u=2i-3j+k,v=-3i+3j+2k,w=i+j+3k

v脳v

Short Answer

Expert verified

The required cross product is0.

Step by step solution

01

Step 1. Given Information  

We are given three vectors u,v,wand we need to find the cross product of v脳v.

02

Step 2. Finding cross product  

v=-3i+3j+2k

The required cross product is

v脳v=ijk-332-332=i3232-j-32-32+k-33-33=i(3.2-3.2)-j((-3).2-(-3).2)+k((-3).3-(-3).3)=0
