If `sin6^@ sin54^@ sin66^@=(lambdasqrta-b)/c`, `a,b,c,lambda in Q^(+)`, then

If sin6^(@)sin42^(@)sin54^(@)sin66^(@)sin78^(@)=(sqrt(a)+b)/(c),a,b,c in N where b&c are relatively prime,then value of (a+b+c) is

a sin A-b sin B=c sin(A-B)

a sin A-b sin B=c sin(A-B)

a sin A-b sin B=c sin(A-B)

If A+B+C= pi and (sin 2 A + sin 2B + sin 2 C)/(sin A + sin B + sin C ) = lamda sin ((A)/(2)) sin ((B)/(2)) sin ((C )/(2)) , then the value of lamda must be

If sin A/sin C=sin(A-B)/sin(B-C) then show that a^2,b^2,c^2 are in arithmetic progression

If p = sin (A-B) sin (C-D) q = sin (B-C) sin (A-D) , r = sin (C-A) sin (B- D) then

In Delta ABC, if sin A: sin C=sin (A-B): sin (B-C) , then a^2,b^2,c^2 are in

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