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

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

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

Within what limits must (A)/(2) lie if 2sin((A)/(2))=sqrt(1+sin A)-sqrt(1-sin A)

For A=460^(@), show that 2sin((A)/(2))=-sqrt(1+sin A)-sqrt(1-sin A)

If A=580^(@), prove that 2sin((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 A=340^(@) " then " sqrt(1- sin A)-sqrt(1+ sin A)=
