[" If "sin x cos y=(1)/(4)" and "],[3tan x=4tan y" then "sin(x-y)=]

If sin x cos y=(1)/(4) and 3tan x=4 then sin(x-y)=

If tan 3x.tan 3y = 1, then sin(x+y)=?

Solve for x, y: {sin x cos y = (1) / (4), 3tan x = tan y

If 5 sin x cos y = 1, 4 tan x = tan y, then

If 5 sin x cos y = 1, 4 tan x = tan y, then

If 5 sin x cos y = 1, 4 tan x = tan y, then

If sin x + sin y= (1)/(2) and cos x + cos y=1 , then tan (x+y) =______

I : If cos x + cos y=1/3 , sin x+sin y=1//4 " then " cos (x+y)=7//25 II : If cos x + cos y=1//3 , sin x + sin y=1//4 " then " sin(x+y)=24//25

Solve : 5 sin x cos y = 1, 4 tan x = tan y .

If cos x+ cos y = 1//3 , sin x + sin y=1//4 " then " cos (x+y)=
