" 4."(sqrt(sin A)-sqrt(sin B))/(sqrt(sin A)+sqrt(sin B))=(a+b-2sqrt(ab))/(a-b)

In any Delta ABC, then minimum value of 2020sum(sqrt((sin A)))/((sqrt(sin B))+sqrt((sin C))-sqrt((sin A)))) must be

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))

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 tanx=b/a then sqrt((a+b)/(a-b))+sqrt((a-b)/(a+b))= ........................... A) (2 sin x)/(sqrt(sin2x)) B) (2 cos x)/(sqrt(cos2x)) C) (2 cos x)/(sqrt(sin2x)) D) (2 sin x)/(sqrt(cos2x))

If (sin A)/(sin B)=(sqrt(3))/(2) and (cos A)/(cos B)=(sqrt(5))/(2) then tan A+tan B is equal to
