# How do you write vector U = 6 and Theta = 45 degrees in cartesian form?

Nov 22, 2015

$x = r \cos \theta$
$y = r \sin \theta$

#### Explanation:

$x = 6 \cos 45 = 6 \frac{\sqrt{2}}{2} \approx 4.24$

$y = 6 \sin 45 = 6 \frac{\sqrt{2}}{2} \approx 4.24$

Cartesian Form : $\left(4.24 , 4.24\right)$

hope that helped
