Phương trình tanx = 1 có nghiệm nào nằm trên trục hoành hoặc trục tung không?

If (1+√1+x)tanx=1+√1−x, then sin 4x is equal to · The correct Answer is:C · We have, tanx=1+√1−x1+√1+x ⇒tanx=1+√1−sinθ1+√1+sinθ,wherex=sinθ ⇒tanx=1+cosθ2−sinθ21 ... 1 + tog 1 1 [1+ log 1/2). 11- log 1 / 11. = 1- log 1. + ...
