Question
Find the angle between $\mathbf{u}$ and $\mathbf{v}$ in the given exercise.Exercise 21
Step 1
The dot product is given by the product of the corresponding elements of both vectors. So, $$\mathbf{u} \cdot \mathbf{v} = (0.9 \times -4.5) + (2.1 \times 2.6) + (1.2 \times -0.8) = -4.05 + 5.46 - 0.96 = 0.45$$ Show more…
