All the three are different from (-3, 1.236)
Explanation:
r = sqrt(x^y + y^2), theta = tan ^(-1) (y/x)
Polar coordinates for
1. (-3, 1.906)
- (3, -7.518)
- ( 3, 5.047)
- (-3, 1.236)
-
(-3, 1.906)
#r ~~ 3.5543# ,#theta) ~~ -43.4292^0# -
(3, -7.518)
#r ~~ 8.0945# ,#theta ~~ --68.2459^0# -
( 3, 5.047)
#r ~~ 5.8713# ,#theta ~~ -59.2722^0# -
(-3, 1.236)
