If in a `DeltaA B C ,sinA ,sinB ,sinC` are in `AP` then

If in aDeltaABC,sinA,sinb,sinC are in A.P ., then

If in a triangle ABC, sinA, sinB,sinC are in A.P., then

If any DeltaABC, if sinA,sinB,sinC are in A.P. and the maximum value of tan(B/2)=lambda, then 1/lambda^2 is -

For DeltaABC , sinA + sinB + sinC

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

In a Delta ABC |[1,1,1],[1+sinA,1+sinB,1+sinC][sinA+sin^2A,sinB+sin^2B,sinC+sin^2C]|=0

In DeltaABC , prove that: sinB+sinC gt sinA

In DeltaABC , prove that: sinB+sinC gt sinA

If in a triangle ABC , (sinA+sinB+sinC)(sinA+sinB-sinC)=3sinAsinB then
