# What is the Cartesian form of ( 6, (-5pi)/2 ) ?

Nov 2, 2016

The Cartesian form is $\left(0 , - 6\right)$

#### Explanation:

Use the equation, $x = r \cos \left(\theta\right)$, to find the x coordinate:

$x = 6 \cos \left(\frac{- 5 \pi}{2}\right)$

$x = 0$

Use the equation, $y = r \sin \left(\theta\right)$, to find the y coordinate:

$y = 6 \sin \left(\frac{- 5 \pi}{2}\right)$

$y = - 6$
