plz ans fast I have to submit tomorrow only plz jaldi

(1+ tan2A) / (1+ cot2A)
= (1+ tan2A) / (1+ 1/tan2A)
= (1+ tan2A) / [(tan2A+ 1)/tan2A)]
= tan2A
I think ....
= (1+ tan2A) / (1+ 1/tan2A)
= (1+ tan2A) / [(tan2A+ 1)/tan2A)]
= tan2A
I think ....

ya u r ans is right I'm sorry I was confused
but there is a mistake
that u had proved only LHS u have not proved RHS
we have to prove that both r equal
I have did it..
but where u have proved RHS
are if ur ans came tan^A but only from one side

one question
how we could know that we have to prove both the sides not only one side
??
if you can proof by solving only one side, then it is best, but if you are not able to do so, then go for both. hope you understand..

thx understand
