It does ! But you have to avoid 2 mistakes : 1) The brackets on wrong place 2) x may not be Pi/2 In[4]:= FullSimplify[ArcTan[Cos[x], Sin[x]], x >= 0 && x < Pi/2] Out[4]= x -----Message d'origine----- De : fizzy [mailto:fizzycist at knology.net] Envoyé : lun., 28. mars 2005 09:42 À : mathgroup at smc.vnet.net Objet : [mg55526] Simplifying ArcTan Why does FullSimplify[ ArcTan[ Cos[x], Sin[x] , x>=0 && x <= Pi/2 ] not output x ?
