Find the exact value of the expression sin pi3 cos pi2 cos

Find the exact value of the expression sin pi/3 cos pi/2 + cos pi/3 sin pi/2 sin pi/3 cos pi/2 + cos pi/3 sin pi/2 =

sin(a)cos(b)+cos(a)sin(b) =sin(a+b)

sin(_/3)cos(_/2)+cos(_/3)sin(_/2) =sin(_/3+_/2)

sin(_/3)cos(_/2)+cos(_/3)sin(_/2) =sin(5_/6)

sin(_/3)cos(_/2)+cos(_/3)sin(_/2) =1_/2

Find the exact value of the expression sin pi/3 cos pi/2 + cos pi/3 sin pi/2 sin pi/3 cos pi/2 + cos pi/3 sin pi/2 = Solutionsin(a)cos(b)+cos(a)sin(b) =sin(a+b
