mukushla Group TitleBest ResponseYou've already chosen the best response.6
is this correct?\[\tan^{1}x +\tan^{1}y+\tan^{1}z=\tan^{1}\frac{x+y}{1xy}+\tan^{1}z\\=\tan^{1}\frac{z+\frac{x+y}{1xy}}{1z\frac{x+y}{1xy}}=\tan^{1}\frac{x+y+zxyz}{1xyxzzy}\] so its valid

Just remember that it is not valid for x belonging to R due to the domain range conditions you may need to add subtract pi. Otherwise its fine.
