Re: [Maxima-discuss] Fwd: [wxmaxima] Strange symmetry of acoth(x), area cotangens hyperbolicus function (#552)

[David S. <d.s...@go...>]

I believe this is caused by line 354 in "trigi.lisp":

(setf (get '%acoth 'reflection-rule) #'even-function-reflect)

change it to:

(setf (get '%acoth 'reflection-rule) #'odd-function-reflect)

Best regards,
David
