If `A+B+C=pi`, then `sinA-sinB+sinC=`

In triangleABC,A+B+C=pi ,show that sinA+sinB+sinC=4cos(A/2)cos(B/2)cos(C /2)

If A+B+C=pi , prove that : sinA+sinB+sinC= 4cos( A/2 )cos( B/2) cos(C/2)

If A+B+C=pi , prove that : sinA+sinB+sinC= 4cos, A/2 cos, B/2 cos, C/2

If A,B,C are th angle of a equilateral DeltaABC , then |(sin2A,sinC,sinB),(sinC,sin2B,sinA),(sinB,sinA,sin2C)|=

If A+B+C = pi and A, B, C are angle of /_\ ; then show sinA + sinB + sinC < (3 sqrt(3))/2 .

If A+B+C=pi , Prove that sin2A+sin2B+sin2C=4sinA.sinB.sinC

Prove that If (b+c)/5 = (c+a)/6 = (a+b)/7 then sinA : sinB : sinC = 4:3:2

For DeltaABC , sinA + sinB + sinC

If A+B+C=pi , prove that : sinA cosB cosC +sinB cosC cosA + sinC cosA cosB = sinA sinB sinC .
