In a `Delta ABC` , If a is the arithmetic mean and `b,c(b!=c)` are the geometric means between any two positive real number then `(sin^3B+ sin^3C)/(sinAsinBsin C)=`

In a triangle ABC,if a is the arithemetic mean and b,c (b ne c) are the two geometric means between any two positive real number then (sin^3 B +sin^3 C)/( sin A sin b sin C) =

If a be the arithmetic mean and b, c be the two geometric means between any two positive numbers, then (b^3 + c^3) / abc equals

In any Delta ABC, sum a sin (B -C) =

In any Delta ABC, sum a sin (B -C) =

In Delta ABC, sum a^3 sin (B-C) =

If 'a' is the Arithmetic mean of b and c, 'b' is the Geometric mean of c and a, then prove that 'c' is the Harmonic mean of a and b.

If ‘a', is the Arithmetic mean of b and c, 'b', is the Geometric mean of c and a, then prove that 'c' is the Harmonic mean of a and b.

In Delta ABC, if a:b:c=3:4:5 , then sin A:sin B:sin C =

In Delta ABC if a:b:c=3:4:5 then sin A:sin B:sin C is

In Delta ABC,sum a^(3)sin(B-C)
