(a)/(sin A)=(b)/(sin B)=(c)/(sin C)

If the angles A,B and C of a triangle ABC are in an A.P with a positive common difference such that the smallest angle is one third of the largest angle, and the sides a, b and c are the sides opposite to the angles A ,B and C such that (a)/(sin A)=(b)/(sin B)=(c)/(sin C) then the ratio of the longest side to that of the shortest side will be

In any Delta ABC, prove that (sin A)/(a)=(sin B)/(b)=(sin C)/(c) by vecter method.

In DeltaABC , if (sin A)/(c sin B) + (sin B)/(c) + (sin C)/(b) = (c)/(ab) + (b)/(ac) + (a)/(bc) , then the value of angle A is

In DeltaABC , if (sin A)/(c sin B) + (sin B)/(c) + (sin C)/(b) = (c)/(ab) + (b)/(ac) + (a)/(bc) , then the value of angle A is

In DeltaABC , if (sin A)/(c sin B) + (sin B)/(c) + (sin C)/(b) = (c)/(ab) + (b)/(ac) + (a)/(bc) , then the value of angle A is

If A,B,C are acute angles then prove that: (sin A)/(sin B)+(sin B)/(sin C)+(sin C)/(sin A)<=(A)/(B)+(B)/(C)+(C)/(A)<=(tan A)/(tan B)+(tan B)/(tan C)+(tan C)/(tan A)

For any acute angled DeltaABC find the maximum value of (sin A)/(A) +(sin B)/(B) +(sin C)/(C)

(cos A)/(sin B sin C)+(cos B)/(sin C sin A)+(cos C)/(sin A sin B)=2

Prove that in any triangle ABC, (sin A)/a= (sin B)/b=(Sin C)/c .
