Summary

0005202: bad documentation for atan2

Description

the documentation associated to atan2 is :
"atan x y returns the arc tangent of y /. x. The signs of x and y are used to determine the quadrant of the result. Result is in radians and is between -pi and pi."

But it should be
"atan y x returns the arc tangent of y /. x. The signs of x and y are used to determine the quadrant of the result. Result is in radians and is between -pi and pi."

x and y are swapped !!!!!

Notes
(0005764) william (reporter) 2011-01-12 01:37	also note that "atan2" should be in place of "atan" in the documentation

(0005765) Christophe Troestler (reporter) 2011-01-12 14:05	FWIW, the documentation is fine in 3.11.2.
