# What is the Cartesian form of ( -7 , (25pi)/12 ) ?

Apr 16, 2017

$\left(- 6.761 , - 1.811\right)$

#### Explanation:

Use the parametric form to find the $x$ and $y$:

$x = r \cos \theta$

$y = r \sin \theta$

Plug into these formulas:

$x = - 7 \cos \left(25 \frac{\pi}{12}\right) \approx - 6.761$

$y = - 7 \sin \left(25 \frac{\pi}{12}\right) \approx - 1.811$

Now we have $x$ and $y$. We just need to write them together:

$\left(- 6.761 , - 1.811\right)$
