hello users ....
################################
we have given that:-
tan (x+y) = 3/4 and tan (x-y) = 1/3
we have to find:
tan 2x = ?
solution :-
we know that :
Here;
tan (x+y) = 3/4
=> .........(1.)
and
tan (x -y) = 1/3
=> ............(2.)
now ;
adding (1.) and(2.), we get ;
= 2x =
=>
=>
=>
=> 2x =
=> tan 2x = 13 / 9 answer
