Find the angle between the vectors. U=< -4,-3> V = < -1,5>

kati45 [8]

Step-by-step explanation:

The formula for the angle between vectors

$\alpha = \cos {}^{ - 1} ( \frac{uv}{ |u| |v| } )$

To multiply vectors, multiply the first component and multiply the second component and add them.

(-4*-1) + (-3*5)= 4-15=-11.

To find magnitude of vectors, use the Pythagorean theorem

$u = \sqrt{ { - 4}^{2} + { - 3}^{2} } = 5$

$v = \sqrt{ - 1 {}^{2} + 5 {}^{2} } = \sqrt{26}$

$|u| |v| = 5 \sqrt{26}$

Know we have,

$\alpha = \cos {}^{ - 1} ( \frac{7}{5 \sqrt{26} } )$

$\alpha = 105.94$

in degrees,

$\alpha = 1.849$

in radians
