If f(A) `sqrt((1+sinA/2)+sqrt(1 sinA/2))/sqrt((1+sinA/2)sqrt(1-sinA/2))` then

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

sqrt((1-sinA)/(1+sinA))=secA-tanA

sqrt((1-sinA)/(1+sinA))=secA-tanA

In any DeltaABC, then minimum value of 2020sum(sqrt((sinA)))/((sqrt((sinB))+sqrt((sinC))-sqrt((sinA))) must be

Prove that : sqrt((1+sinA)/(1-sinA))-sqrt((1-sinA)/(1+sinA))=2tanA

If 2 sin""A/2=sqrt(1+sinA)+sqrt(1-sinA,)then A/2 lies between,

If A=580^(0) then -sqrt(1+sinA)-sqrt(1-sinA)=

In any DeltaABC , then minimum value of 2020sum (sqrt((sinA)))/((sqrt((sinB))+sqrt((sinC))-sqrt((sinA)))) must be

sqrt((1+sinA)/(1-sinA))
