sqrt((1-sin17)/(1+sin A))

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

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

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

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

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

GIven (pi)/(2)

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))

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

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