If (sin(x+y))/(sin(x-y))=(a+b)/(a-b), show that (tan x)/(tan y)=(a)/(b)

If ( sin (x+y))/(sin (x-y))=(a+b)/(a-b) " then " ( tan x)/(tan y)=

If (sin (x+y))/(sin (x-y))=(a+b)/(a-b) , show that a tan y=b tan x

Prove that ,,(sin(x+y))/(sin(x-y))=(tan x+tan y)/(tan x-tan y)

Prove that: (sin(x+y))/(sin(x-y))=(tan x+tan y)/(tan x-tan y)

IF ( sin ( x+y) )/( sin (x-y) ) = (a+b)/( a-b) , then ( tan x)/( tan y) =

(b)If (sin (x+y)/sin(x-y))=(a+b)/(a-b) show that a tan y=b tan x .
