`b^(2) sin 2C + c^(2) sin 2B = 2bc sin A`.

b^(2) sin 2C + C^(2) sin 2B = 2 b sin A

In any triangle ABC, prove that : b^2 sin 2C + c^2 sin 2B = 2 bc sin A .

In triangle ABC, b^(2) sin 2C + c^(2) sin 2B = 2bc where b = 20, c = 21 , then inradius =

In triangle ABC, b^(2) sin 2C + c^(2) sin 2B = 2bc where b = 20, c = 21 , then inradius =

lf in DeltaABC,b^(2)sin 2C + c^(2) sin 2B = 2bc,then the triangle is

lf in DeltaABC,b^(2)sin 2C + c^(2) sin 2B = 2bc,then the triangle is

In any Delta ABC, prove that b^(2)sin2C+c^(2)sin2B=2bc sin A=4Delta

In triangle ABC, b^(2), sin2C+c^(2) sin 2B-2bc where b=20 c=21 then inradius =

In a triangle ABC, if a, b, c are in A.P. and (b)/(c) sin 2C + (c)/(b) sin 2B + (b)/(a) sin 2A + (a)/(b) sin 2B = 2 , then find the value of sin B
