Convert each of the following points from rectangular coordinates to polar coordinates.
(1, 1)
A) (sqrt(2), pi/4)
B) (sqrt(2), 3pi/4)
C) (sqrt(2), pi/4)
D) (sqrt(2), 3pi/4)
E) None of These

the angle is in QII, so (B)
Generally, the radius is expressed as a positive number, though (sqrt(2),pi/4) would also have been correct.
