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

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

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

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)

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

sqrt((1-sin A)/(1+sin A))=sec A-tan A

The value of (sqrt(1 + sin x )+sqrt(1 - sin x))/(sqrt(1 + sin x )-sqrt(1-sin x)) is equal to
