" If "A=340^(@)" then "sqrt(1-sin A)-sqrt(1+sin A)=

sqrt ((1-sin A) / (1 + sin A))

sqrt((1+sin x)/(1-sin x))

If A=340^(@), prove that 2sin((A)/(2))=-sqrt(1+sin A)+sqrt(1-sin A) and 2cos((A)/(2))=-sqrt(1+sin A)-sqrt(1-sin A)

The value of (sqrt(1+sin A)+sqrt(1-sin A))/(sqrt(1+sin A)-sqrt(1-sin A)) (When |Tan(A)/(2)|lt1 and |(A)/(2)| is acute) is

2 (sin A) / (2) = - sqrt (1 + sin A) -sqrt (1-sin A)

If -(pi)/(4)lt A lt (pi)/(4) , then (sqrt(1+sin 2 A)+sqrt(1-sin 2 A))/(sqrt(1+sin 2 A)-sqrt(1-sin 2 A)) is equal to
