Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! Change the polar coordinates (4Sqrt2, 3pi/4), to rectangular coordinates.
--------
You have r=4sqrt2
You have theta=(3/4)pi
------------
Conversion formulas:
x=rcos(theta)
y=rsin(theta)
------------------
x=4sqrt2cos[(3/4)pi]=-4
y=4sqrt2sin[(3/4)pi]=4
==========
