Answer» if A=30degree veryfie that tan2A=2tanA/1-tan2A This QUESTION answer is very simple R. H. S: tan2A/1-tan2A =2.(30degree)/1- 2.(30degree)2 =2.(1/root3)/2.(1/root3)2 =(2/root3)/(2/3) =(2/root3).(3/2) =(3/root3) =(root3 .root3)/root3 =root3 L. H. S: tan2A =2.(30degree) =60DEGREE . : tan(60degree)=root3 . : L. H. S=R.H.S (proved) ( Ans)
