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

In any DeltaABC , prove that Sigma (sqrt(sinA))/(sqrt(sinB)+sqrt(sinC)-sqrt(sinA)) ge 3 and the equality holds if and only if triangle is equilateral.

In any DeltaABC , prove that Sigma (sqrt(sinA))/(sqrt(sinB)+sqrt(sinC)-sqrt(sinA)) ge 3 and the equality holds if and only if triangle is equilateral.

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

(sqrt(sinA)-sqrt(sinB))/(sqrt(sinA)+sqrt(sinB)) = (a+b-2sqrt(ab))/(a-b)

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

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

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

If a DeltaABC , the value of sinA+sinB+sinC is

In any triangleABC , prove that (sqrt(sinA)-sqrt(sinB))/(sqrt(sinA) + sqrt(sinB)) = (a+b-2sqrt(ab))/(a-b) [Hint : (a-b)^(2) = a^(2)+b^(2)-2ab ]
