If in a`DeltaABC, sin A, sin B, sin C` are in A.P., show that `3 tan, A/2 tan, C/2 = 1`

If in a !ABC , sin A, sin B and sin C are in A.P, then

In any triangle ABC, if sin A , sin B, sin C are in AP, then the maximum value of tan ""B/2 is

If, in a /_\ABC , it is given that a^(2), b^(2), c^(2) are in an A.P., show that tan A, tan B, tan C are in the H.P.

If in a DeltaABC, sin A: sin C = sin (A - B): sin (B-C), then a^(2), b^(2), c^(2) are in

In a Delta ABC if tan B=(2sin A sin C)/(sin(A+C)) then tan A,tan B,tan C are in

If sides a,b,c of Delta ABC are in A.P., then : sin (A/2) cdot sin (C/2)/(sin (B/2) =
