(tanx+coty)/(tanxcoty)=tany+cotx

Question

shubhamsrg · Answer

whats the ques? relation between x  and y ?

anonymous · Answer

what to do with it..? if you are saying to prove LHS=RHs that is pretty obvious..

anonymous · Answer

the question in verify the identity. i have to solve the left side of the equation to make it look like that right.

shubhamsrg · Answer

infact @rs32623 ,,LHS = RHS only when x=2npi +pi/4

anonymous · Answer

@shubhamsrg and what about y?

shubhamsrg · Answer

its a bit incorrect..please re check the ques..
according to this,,LHS = tan y+ tan x ,,which is not your RHS

shubhamsrg · Answer

@rs32623 y can be anything,,as tan y  is common to both LHS and RHS

anonymous · Answer

LHS=(tanx+coty)/(tanxcoty)
=tanx/(tanxcoty)+coty/(tanxcoty)
=1/coty+1/tanx
=tany+cotx=RHS

hence proved.

lol..am so sorry sir,,i by mistake treated 1/tan x as tan x.. really really sorry..
yes you're right ^_^
