If sin x-sin y-1-2 and cos x-cos y-1- then tan x-y-

The correct option is D 4/3 sin x + sin y =1/2, cos x + cos y = 1. So tan x+y/2 =1/2 So tan (x+y) = 4/3 nbsp; ...

tan (x + y) =

cos x + cos y = \frac{1}{3}, sin x + sin y = \frac{1}{4}

cos (x + y) = \frac{- 7}{25}

sin x + sin y = \frac{1}{4}, sin x - sin y = \frac{1}{5}

4 cot (\frac{x - y}{2}) = 5 cot (\frac{x + y}{2})

\frac{sin x - sin y}{cos x + cos y} = tan \frac{x - y}{2}

\frac{sin x - sin y}{cos x + cos y} = tan \frac{x - y}{2}
