त्रिभुज ABC में , ` cosec A ( sin B cos C+ cos B sin C) ` बराबर है

In Delta ABC, cscA (sin B cos C + cos B sin C) =

In a triangle, cosec A (sin B cos C + cos B sin C) is equal to :

A+B+C=180^(@)rArr Cosec A[sin B cos C+cos B sin c]=

If A+B+C=180^(@) then the value of cosec A(sin B cos C+cos B sin C) is

In a Delta ABC , 2 sinA cos B + 2 sin B cos C + 2 sin cos A = sin A + sin B + sin C, then Delta ABC is

In a Delta ABC , 2 sinA cos B + 2 sin B cos C + 2 sin cos A = sin A + sin B + sin C, then Delta ABC is

Prove that sin(A+B+C)=sin A cos B cos C+cos A sin B cos C+cos A cos B sin C-sin A sin B sin Ccos(A+B+C)=cos A cos B cos C-cos A sin B sin C-sin A cos B sin C-sin A sin B cos C

If : A+B+C=pi, "then"" "sin ^(2) A +sin^(2)B - sin ^(2)C= A) 2 cos A * cos B * sin C B) 2 cos B * cos C * sin A C) 2 sin A * sin B * cos C D) 2 sin B * sin C * cos A

if A + B + C = pi then (cos A) / (sin B sin C) + (cos B) / (sin C sin A) + (cos C) / (sin A sin B) =
