" 8."sqrt(1+sin A)=-(sin(A)/(2)+cos(A)/(2))" is true if "

sqrt(1+sinA)=-(sin(A/2)+cos (A/2)) is true if :

sqrt(1+sin A)=-(sin backslash(A)/(2)+cos backslash(A)/(2)) is true if

If sqrt(1- sin A)= sin "" A/2 - cos "" A/2 could lie in quadrant

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

tan ""A/2 is equal to.............. A) sqrt((1- sin A)/( 1+ sin A)) B) sqrt((1+ sin A)/(1- sin A)) C) sqrt((1 -cos A)/(1 + cos A)) D) sqrt((1 +cos A)/(1- cos A))

sin^(-1){cos(sin^(-1)(sqrt(3)/2))}

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,), wh e n(A)/(2)=278^(@)
