    sin3A + sinA = 2*sin2A*cosA

    sin2A = 2*sinA*cosA



    2*sin2A*cosA + 2*sinA*cosA =

    = 2*cosA*(sin2A + sinA) =

    = 2*cosA*2*sin(3A/2)*cos(A/2) =

    = 4*cos(A/2)*cosA*sin(3A/2)

    sqr(sinA(alpha))+sqr(cosB(beta)) = 1
    It's not about what science can do for you. It's all about what you can do for the science.
