Answer

The values are compuv=0, proju v=0 and the component of v orthogonal to u is -4,-6,3.

1Step 1. Given information.

The given vectors are:

u=3,-1,2 and v=-4,-6,3

2Step 2. Find the component of the projection of v onto u.

compuv=u·vuu=3,-1,2 and v=-4,-6,3u·v=3-4+-1-6+23=-12+6+6=0u=32+-12+22=9+1+4=14

Then,

compuv=u·vu=014=0

Therefore, compuv=0.

3Step 3. Find the vector projection of v onto u .

proju v=u·vu2u=01423,-1,2=0

Therefore, the vector projection of v onto is proju v=0

4Step 4. Find the component of v orthogonal to u .

The component of v orthogonal to u is v-projuv.

v-projuv=-4,-6,3-0=-4,-6,3

Therefore, the component of v orthogonal to u is -4,-6,3.
