Answer: 1.8°
Step-by-step explanation:
To calculate the angle between the vectors u and v we use the formula of the dot product.
The dot product between two vecotores is:
Where x is the angle between the vectors
As we know the components of both vectors, we calculate the dot product by multiplying the components of both vectors
Then:
Now we calculate the magnitudes of both vectors
Then:
Now we solve the equation for x
