" Q."1((1+sin-1)(1+sin B)(1+sin C)=(1-sin-1))/((1-sin B)(1-sin C)=k rarr k=)

(1 + sin A) (1 + sin B) (1 + sin C) = (1-sin A) (1-sin B) (1-sin C) = k rArr k

If k=(1+ sin A) (1+ sin B)(1+ sin C)=(1- sin A) (1- sin B) (1- sin C) " then " k=

If ^( If )(1+sin A)(1+sin B)(I+sin C)=(1-sin A)(1-sin B)(1-sin C) ,then each side is equal to

(1) ((1-cos B)(1+cos B))/((1-sin B)(1+sin B))=(1)/(3)

If (1 + sin alpha) (1 + sin beta) (1 + sin gamma) = (1 - sinalpha) ( 1 - sin beta) ( 1- sin gamma) = k . find the value of k?

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))

(a) sin1^(@)>sin1(b)sin1>sin1^(@)(c)sin1=sin1^(@)

If f(x) = frac{sin^(-1)x}{sqrt (1-x^2)} , g(x)=e^(sin^(-1)x) , then int f(x)g(x) dx =........................ A) e^(sin^(-1)x) (sin^(-1)x-1) + c B) e^( sin^(-1)x) (1- sin^(-1)x) + c C) e^(sin^(-1)x) (sin^(-1)x+1) + c D) -e^(sin^(-1)x) (sin^(-1)x-1) + c
