# Finding Dot ProductsIn Exercises 3–10, find(a) u ⋅ v (b) u ⋅ u (c) ‖ v ‖ 2 (d) ( u ⋅ v ) v , and(e) u ⋅ ( 3 v ) . u = 2 i + j − 2 k v = i − 3 j + 2 k

(a)

To determine

To calculate: The value of uv where u=2i+j2kandv=i3j+2k.

Explanation

Given:

The provided vectors are u=2i+j2kandv=i3j+2k ;

Calculation:

The dot product of the vectors u=u1i+u2j+u3kandv=v1i+v

(b)

To determine

To calculate: The value of the vector uu, when the vectors are u=2i+j2kandv=i3j+2k.

(c)

To determine

To calculate: The value of the vector v2 when u=2i+j2kandv=i3j+2k.

(d)

To determine

To calculate: The value of (u.v)v, when the vectors are u=2i+j2kandv=i3j+2k.

(e)

To determine

To calculate: The value of u(3v) when the vectors u=2i+j2kandv=i3j+2k.
