If `2cos(A/2)=sqrt(1+sin A)+sqrt(1-sin A)` ,then `(A)/(2)` lies between

If 2 sin""A/2=sqrt(1+sinA)+sqrt(1-sinA,)then A/2 lies between,

IF 2cos((A)/(2))=sqrt(1+sin A)-sqrt(1-sin A) then the range of (A)/(2)

2cos((A)/(2))=+-sqrt(1-sin A)+-sqrt(1+sin A),when(A)/(2)=-140^(@)

2sin((A)/(2))=-sqrt(1+sin A)+sqrt(1-sin A) if A=340^(@)

2cos((A)/(2))=+-sqrt(1-sin A)+-sqrt(1+sin A,), wh e n(A)/(2)=278^(@)

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)

In the formula 2cos((A)/(2))=+-sqrt(1+sin A)+-sqrt(1-sin A) if two positive signs are taken
