Question

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

Answer 1

whats the ques? relation between x and y ?

Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

@shubhamsrg and what about y?

Answer 6

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

Answer 7

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

Answer 8

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

hence proved.

Answer 9

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