Let
Z1= cosA + i sinA where Re(Z1) = cosA & Im(Z1) = sinA
Z2= cosB + i sinB where Re(Z2) = cosB & Im(Z2) = sinB
Z1*Z2=(cosA + i sinA)*(cosB + i sinB)=cosA*cosB+cosA* (i sinB)+(i sinA)* cosB+(i sinA)*(i sinB)
= cosA*cosB + i (cosA*sinB + sinA*cosB) +(-1) sinA*sinB
= (cosA*cosB - sinA*sinB) + i (cosA*sinB + sinA*cosB)
Hence,
Re ( Z1*Z2) = (cosA*cosB - sinA*sinB) = Re(Z1) *Re(Z2) - Im(Z1) *Im(Z2)
