Sin a + sinb
Webb13 feb. 2016 · If sinA + sinB + sinC = cosA + cosB + cosC = 0, prove that cos3A + cos3B + cos3C = 3cos(A + B + C). My solution: From the given, cos3A + cos3B + cos3C = 3cosAcosBcosC Now, L.H.S = cos3A + cos3B + cos3C = 4cos3A − 3cosA + 4cos3B − 3cosB + 4cos3C − 3cosC = 12cosAcosBcosC. My solution ends here.
