b. (2 rt2, 3pi/4)

I cant figure this one out

**drwls**, Wednesday, March 26, 2008 at 5:37amI don't know what they call the radius 2 rt2.

Whatever the polar-coordinate radius is, multiply it by cos 3pi/4 to get x and sin 3pi/4 to get y.

cos 3pi/4 = cos 135 degrees = -1/(sqrt 2)

sin 3pi/4 = sin 135 degrees = 1/(sqrt 2)
