$x = - 5, 66$ $x=-5,66$
$y = - 5, 66$ $y=-5,66$

enter image source here

$P = (8, 5 \frac{π}{4})$ $P=(8,5pi/4)$

$P = (x, y) rectangular form$ $P=(x,y)" rectangular form"$

$r = 8$ $r=8$

$x = 8 \cdot cos (5 \frac{π}{4})$ $x=8*cos (5pi/4)$

$x = - 5, 66$ $x=-5,66$

$y = 8 \cdot sin (5 \frac{π}{4})$ $y=8*sin(5pi/4)$

$y = - 5, 66$ $y=-5,66$

How do you convert (8, 5pi/4)(8,5π4)(8, 5pi/4) to rectangular form?
