Question 1080853
.
<pre>
(2sqrt(2),315°)  is your original point.


(2sqrt(2),315°+360°) = (2sqrt(2), 675°) is another presentation of the same point (#2);


(2sqrt(2),315°+2*360°) = (2sqrt(2), 1035°) is the third presentation of the same point (#3);


(2sqrt(2),315°-360°) = (2sqrt(2), -45°) is the fourth presentation of the same point (#4).
</pre>


In principle, there are INFINITELY many other presentations of the same point in polar coordinate.


They differ by the argument value.


And the difference in the argument values between different presentations of the same point is a multiple of 360° (the full rotation).
