Theorem 4 :If `A+B+C=pi` then 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=180 , 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=0^(@) then prove that sinA+sinB-sinC=-4"cos"A/2"cos"B/2"sin"C/2

If A+B+C=180 , prove that: sinA+sinB+sinC=4cosA/2cosB/2cosC/2

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